On the design of commercial off-the-shelf machmeter with CANaerospace interface

The paper is aimed at the design, implementation and experimental functional verification of the machmeter manufactured using common available components and pressure sensors. As a basis of the machmeter a universal platform Arduino UNO R3 was utilized. Projected Mach number measurement range is from 0.4 to 1.2. That means for subsonic and transonic speed of flight measurement. The paper includes experimental results and a detailed description of the error correction process.
