Next time we’ll focus on the MPRBC rotary pistons RdM
Piston Octagonal in Deformable Controlled Geometry (POGDC)
Case study on rotary pistons of MPRBC machines
The pistons of MPRBC machines are subjected to pure bending. Below the answer for 100 Bar pressure
There is a concentration of stresses at the level of the piston neck. This remains below the elastic limit of the steel. It would be easy by redrawing the profile to significantly reduce this maximum stress.

Hi Jam,
No idea about noise. it also depends a lot on the exhaust line.
Given the intrinsic balancing of the motor, one can think that these motors cause less vibrational noise.
At equal power, there will be no more combustion (even slightly less) than for a conventional engine, so not really more noise.
Here are some things to think about.

Note: it is a summary modeling resulting from the theory of the beams, without taking into account the rigidity of the connecting rods and the heads of pistons (the computed stresses thus increase the real stresses).
Nevertheless, the stresses remain well below the elastic limit, in particular if the number of joints is increased (because this limits bending).
Next time, presentation of deformations / stresses of the MPRBC housing.
