    To make launch weapons with further range, higher energy density, better target accuracy, and better control ability are the aims pursued by people for many years. This paper divides the history of launch technology into four stages, which are the biologic, mechanical, chemical, and electromagnetic launch stages. The development trend of the launch technology is discussed, particularly the advantages of the electromagnetic launch (EML) technology. Recently, China has paid great attention to many new technical fields, such as the EML technology. China's programs are mainly confined to fields of basic research, which are collected together in this paper. However, the numbers of papers published from the 12th symposium to the 16th symposium suggest that there are more and more programs in the EML field. View full abstract»

    An active electromagnetic (EM) armor is a new kind of active defense system, which consists of advanced detector, control system, high pulsed-power supply, and EM launcher (EML). Electric energy provided by the high pulsed-power supply can be transformed into kinetic energy of the interception projectile with EML. Hit by interception projectiles, the invading object could be totally destroyed or deviate from its trajectory. In the EML the launch coil is a key component and it could be destroyed when the peak current load exceeds a certain value. In this paper, the structure and working principle of the EML are introduced. By means of ANSYS software, a 3-D finite element model of the EML is established, and multifield coupled analysis (EM-thermal-structural analysis) of the launch coil is accomplished during the loading process. The distribution of temperature, deformation, and stress of the launch coil versus time are achieved. Influence of the current loads on the temperature and strength of the coil are also analyzed. The results indicate that the maximal temperature, deformation, and stress appear at the center of the launch coil and this part is easy to be destroyed. It is well-matched with the experimental results. View full abstract»

    A study was undertaken to determine if a ground-based electromagnetic (EM) acceleration system could provide a useful reduction in launch-to-orbit costs compared with current large chemical boosters, while increasing launch safety and reliability. The study evaluated EM augmentation of the chemical boost capability for a two-stage-to-low-Earth-orbit system, with the extreme case being a complete EM launch. Several EM acceleration options are available, but railguns were chosen for this study. The second stage of the system was assumed to be a chemical rocket or a reusable scramjet to carry a reusable orbiter vehicle into low-Earth orbit. EM launch systems of this type will be governed by the same fundamental principles as tactical guns, but one major difference will be that the EM accelerator track, which may be several kilometers in length, will not be powered only from the “breech” as in a tactical gun, since electrical resistive losses will be unacceptably large. To overcome this, a distributed feed system will be required. This study shows that the capital cost of the pulsed-power system for the EM accelerator will dominate the system economics. Present pulsed-power approaches will require many launches to offset the capital cost. Novel pulsed-power concepts or low-cost manufacturing approaches will need to be developed for such a concept to be economically attractive. View full abstract»

    Induction coil guns are a class of launchers that utilize electromagnetic energy to promote the armature. During launching, the driving coil and the armature will generate a lot of heat which can make the drive coil and the armature melt, thereby affecting the normal work of the entire induction coil gun. However, it is quite difficult to accurately describe the temperature variation of the induction coil gun because of the complexity of its structure. So, the temperature of the launcher is analyzed using the finite element method in this paper. The launcher temperature simulation model is built using ANSYS software, and the temperature distribution of the drive coil and armature is analyzed using the load transfer method. The simulation results show that, without considering magnetoresistance effect and skin effect, the temperature distribution of the drive coil is uniform; the temperature rise of the armature is mainly on the outer surface and in the tail. Finally, the launcher temperature measurement experimental platform is set up and the temperatures of key points are measured, thereby verifying the simulation results. View full abstract»

    The eddy current and force distribution on the plunger of a single-stage induction damper is analyzed for the numerical investigation and design improvement of induction dampers. A 3-D finite-element method is applied to the eddy current analysis of the magnetic field, and the Lorentz force on the plunger is calculated using the nodal force method. The simulation results show that the Lorentz force on the plunger can be increased by installing a ferromagnetic enclosure around the coil. Furthermore, an induction damper model is proposed considering the skin effect of eddy current on the plunger. The results show that the flux interlinking the plunger is increased by reducing the thickness of the plunger. Finally, the dynamic simulation is carried out to verify the design and investigate the dynamic characteristics of the induction damper. The damper with a ferromagnetic groove enclosing the coil is proven to be more effective. View full abstract»

    In order to analyze the launching efficiency and firing accuracy of the reluctance electromagnetic launcher (REML) with different armatures, the working principle of the REML was introduced in brief at first. The effect of different armature structures to launching efficiency and firing accuracy was analyzed in theory. After that, this paper demonstrated a five-stage REML and three kinds of armatures: cylindrical armature (CA), CA with notch (CAN), and CA with tail fin (CATF). The muzzle velocity and the circumradius of projectile impact position for different armatures were got by experiment with the five-stage REML. The experiment results show that the maxim launching efficiency is 2.87% for the CAN, and the minimum circumradius of projectile impact position is 68 mm for the CATF. It can draw the conclusions that the notch in the cross section of armature can weaken or even eliminate the formation of eddy current in the armature, which is beneficial to the improvement of the launching efficiency. It can improve the firing accuracy by furnishing a tail fin at the rear of the armature. View full abstract»

    Performance analysis of a coil launcher is very important for experimental research and electromagnetic optimization design. To check the effect of the improvement and analyze electromagnetic transient in a coil launcher, a field coupling circuit simulation method is introduced in this paper. Initially, the current of drive coils is calculated by the circuit model based on improved current filament method, and then the exciting current is loaded in 2-D axisymmetric field model. The field model is built based on nonoverlapping mortar finite-element method (NO-MFEM). NO-MFEM divides the whole domain into two subdomains: one contains the movable part (armature), and the other contains the source current (coils). The two subdomains are discretized independently and the two sets of meshes are nonconforming on the interface. When the movable part changes its location, it is necessary only to change the node coordinates in movable subdomains and information of mortar nodes and elements. In this paper, performance analysis of a three-stage coaxial induction coil launcher is carried out based on the proposed field-circuit method. The correspondence of the simulation results proves the validity of the field-circuit method. View full abstract»

    Shielding enclosure is very important for a coil launcher system. Shielding performance directly determines the electromagnetic performance of a coil launcher. In this paper, the formulation of the eddy current field involving movement is deduced, and the time step transient finite element method calculation is applied to investigate the shielding performance of a coil launcher. The simulation model of a three-stage coaxial induction coil launcher is built based on ANSOFT MAXWELL software. The transient-simulation model, which is involved in moving conductor eddy current, the pulsed power generator, and the power electronic component, is built as a circuit simulation in MAXWELL schematic module. The circuit model is well coupled with the field model in a transient solver. In every time step, the value of current obtained by the circuit simulation in advance is loaded in the field model as an exciting source to the coils. Three-typical shielding materials, iron, steel, and ferrite are used in 2-D field model to study the influence of shielding enclosure on the electromagnetic performance of the coil launcher. Silicon steel (laminated sheets) is taken in the 3-D field model. Different geometric dimensions of shielding enclosure are also taken into consideration. The speed of the armature and the magnetic field are calculated. The current distribution in the armature and shielding enclosing are displayed as well. Effects of shielding enclosure on the electromagnetic performance are then concluded. A ferrite shielding enclosure will increase the speed of armature obviously. The conductive material will induce eddy currents and decrease the leakage magnetic field outside, that shows excellent shielding performance. The silicon steel shielding enclosure has a similar impact on the speed of the armature to the ferrite, whereas it has better shielding effectiveness than the latter. Research results show that the silicon steel is suitable for the coil launcher shielding enc- osure. View full abstract»

    To demonstrate the multistage induction launch capability and test the accuracy of the simulation result, a small-scale, 4-stage synchronous induction coilgun is designed, fabricated, and tested based on the simulation result. The four coils are stacked end-to-end, forming a barrel, and each coil is energized by the identical pulsed power supply in sequence to create a traveling magnetic wave that accelerates a projectile. The inductance of four coils is tailored by changing the number of turns in order to decrease the pulsed current risetime. The tracking of the projectile location during a launching provides a precise feedback to control when the coils are triggered to create the wave. Two types of the projectiles are tested. A 0.65-kg sleeve projectile is accelerated from rest to 125 m/s with a projectile kinetic energy to capacitor-stored energy efficiency of 6%. A 1-kilogram sleeve projectile is accelerated from rest to 92 m/s with the efficiency of 5%. The solenoid projectile is broken at the bending point when it induces high current. The launcher provides data for model verification and the engineering basis for proceeding with larger multistage system. Further research is to improve the system efficiency and maximize the magnetic coupling between the driving coil and the projectile. View full abstract»

    An improved large-caliber synchronous induction coilgun is designed and tested to demonstrate the launch of 120-mm projectiles. This induction coilgun consists of 15 identical coils forming a long uniform barrel for simple design and fabrication. Fifteen separate coils are fit in a long insulative tube and molded once with elastic insulative material that isolates the coils with the containment. The 15-stage induction coilgun provides a significant improvement in the armature capture effect, system efficiency, and coil structure. A computer simulation model based on the viewpoint of finite element analysis software is developed to predict the performance of the launcher system. Five-kg copper projectiles are accelerated from rest to 220 m/s through the 2.5-m launcher assembly with a projectile kinetic energy to capacitor stored energy efficiency of 14.5%. Further experimental studies are continued. View full abstract»

    A model experiment is an effective method to investigate the working characteristics of electromagnetic coil launcher (EMCL). Results from the model experiment are applied to the prototype study of EMCL, after the scaling relations of physical quantities between model and prototype are determined. A new type of EMCL is designed, and the scaling factor relations of the physical quantities between model and prototype of the EMCL are deduced based on its mathematical model and similarity theory. The scaling model is investigated by simulation. It is shown that the scaling factor relations of the physical quantities are expressed as length-scaling factor, and the scaling model is feasible.

    Helical coil electromagnetic launchers (HEMLs) using rail-fed strategy, local excitation and single-turn commutation, solve the problem of synchronization control perfectly. Through the simulation, a novel helical coil launcher is designed using the basic HEML's structure. A D-shaped cross section armature is proposed to achieve the maximum projectile velocity. The energizing length of the driving coil, as well as, the armature position of the maximum force is determined. The maximum driving force on the armature increases with the increasing coil axial length and the armature acceleration reaches its maximum value when the ratio of axial to radial length of the coil is 1:2. The force distribution of the armature and driving coils is analyzed. View full abstract»

    The solution of large and complex coupled electromechanical problems requires high-performance computing resources. Over the past years, the use of graphic processing units (GPUs) in scientific computing has gained increasing popularity because of their low cost and parallel architecture. In this paper, the authors report the main results of a GPU approach for the parallelization of a research code for electromagnetic launcher analysis. Programming a GPU-based environment poses a number of critical issues that have to be carefully addressed in order to fully exploit system potential. Data have to be properly organized in order to fit the single-instruction multiple-data scheme; data transfer between the host and the device, as well as memory management of the GPU, deserves accurate programming. Two examples of application of the parallelized code have been reported to show the performance improvements that can be obtained in the numerical analysis of both rail and induction launchers.

    A numerical model of radiation has been employed by using a Monte Carlo method and statistical physics to simulate the process of a capillary plasma source for an electrothermal-chemical launcher. The effect of plasma on propellants with different physical parameters is discussed. The plasma-propellant interaction when the radiation model is combined with a thermal model is also discussed. Results show that radiant energy only causes a small field around the plasma injector in the propellant bed. The responses of energy flux and propellant particles to radiation are both on the order of picoseconds. The strong instantaneous radiation is not only the dominant effect of energy transport in hot plasma but is also responsible for the transmission of energy to the propellant particles leading to ignition. This energy skin effect on the propellant-particle surface appears to be the main cause of plasma ignition. View full abstract»

    A thermal model of a switched reluctance linear launcher is presented in this paper. The accuracy of the thermal model is verified by comparing experimental data with those results derived from finite-element method simulation. The temperature distribution of a switched reluctance linear launcher is derived based on the stator copper losses as the main heat power with measured stator winding current by the current sensor. The maximum temperature rise curves under different ambient temperature and different heat power of winding A are studied. The heat dissipation power of four air convection surfaces under different ambient temperature and the different heat power of winding A is also studied. Furthermore, this paper achieves optimization in thickness of the stator plate and in adding fins to the stator plate for heat dissipation with the present model. It is shown that the stator plate is the maximum heat dissipation power surface so that it can be adopted as the main heat dissipation channel and the effect of heat dissipation is obvious by adding fins to the stator plate.

    A nonlinear simulation model of switched reluctance linear launcher drive based on MATLAB platform is presented in this paper. It consists of a three-phase 6/4 structure simple side switched reluctance linear motor, a three-phase asymmetric bridge power converter, and a closed-loop velocity controller, which is integrated with the magnetization curves of the switched reluctance linear motor obtained by the two-dimension finite-element electromagnetic field calculation, the nonlinear electrical network model of the power converter, and the excitation/commutation/velocity control algorithms. Those include mover relative position calculation module, controller module, power converter module, phase winding modules, and velocity calculation module. The simulated phase current waveforms and velocity curves agree well with the tested phase current waveforms and velocity curves experimentally. It is shown that the proposed nonlinear simulation model of the three-phase 6/4 structure switched reluctance linear launcher system is valid. View full abstract»

    In this paper we describe a developed switched reluctance linear launcher system with diagrams and photographs, which consists of a three-phase 6/4 structure simple side-switched reluctance linear motor, a three-phase asymmetric bridge power converter, and a TMS320F28335 DSP digital controller. The acceleration closed-loop control of the mover is proposed and verified for the first time. The acceleration closed-loop control of the mover is implemented by a fuzzy control algorithm. The turn-on angle and the turn-off angle of the main switches in the power converter are fixed, and the triggering signals of the main switches are modulated by the pulse width modulation (PWM) signal. The deviation of the acceleration between the given acceleration and the feedback practical acceleration, and the variation from the deviation of the acceleration are the two input control parameters. The increment of the duty ratio of the PWM signal is the output control parameter. The duty ratio of the PWM signal is regulated based on the fuzzy control algorithm. Flow diagrams of the software, such as the main program, the encoder unit time interrupt subroutine, analog-to-digital converter interrupt subroutine, and the fuzzy control algorithm subroutine are given. The developed prototype is tested experimentally. It is shown that the velocity response of the mover is satisfactory. View full abstract»

    Based on the principle of rotational flux-switching permanent magnet machines, a novel double-sided long primary flux-switching permanent magnet linear motor (FSPMLM) is proposed for electromagnetic launch systems (EMLS). Compared with traditional induction and synchronous linear machines used in EMLS, the proposed motor is more suitable for EMLS because of its high thrust density and simple structure of the secondary. First, the structure and operation principle of the proposed FSPMLM are given and analyzed. Second, considering the longitudinal end effect, the thrust components are analyzed and derived. According to the generation principle of the thrust components, the optimal methods, implemented to reduce the thrust ripple, are obtained and analyzed. In addition, a 2-D transient finite element method is used to investigate the dynamic electromagnetic characteristics of the FSPMLM and the process of electromagnetic launch. Finally, a prototype of single-sided FSPMLM is employed to validate the thrust performance of the proposed machine. View full abstract»

    A slide-contact type linear electromagnetic catapult (SCLEMC) is investigated in this paper. The structure model of SCLEMC is proposed and its working principle and commutation process are analyzed. The thrust model of the SCLEMC is presented. The thrust characteristic of the SCLEMC is researched by means of the method of finite element analysis. The influences of the driving current and the gap between the mover and the stator on the thrust characteristic of the SCLEMC are analyzed. Research shows that the scheme of the SCLEMC is feasible and that the SCLEMC has high efficiency. The commutation process can be automatically realized through three brushes, which can avoid the complex drive and control system. The commutation voltage of commutation turns is not high under the condition of low speed, which does not damage the stator winding and the brushes. The value of the driving current has an important influence on the thrust characteristic of the SCLEMC. The thrust acting on the mover increases with the increase of driving current.
