Webof the air entering the engine at plane 2 (Fig. 1) is depen-dent on the ambient air temperature and the ram rise due to the flight velocity of the aircraft. At plane 3, the tem-perature rise due to compression is added. Up to this point the temperatures are usually below 1000 F, so that they can be measured by thermocouples with relative ease. Web27 feb. 2024 · The compression ratio can be easily found with the following formula: \textrm {CR} = \frac {V_d+V_c} {V_c} CR = V cV d + V c where: V_d V d is the displacement volume – the volume that has been swept by a moving piston. You can calculate it according to the cylinder volume formula: V_d = \tfrac 14 \cdot b^2 \cdot s \cdot \pi V d = 41 ⋅ b2 ⋅s ⋅π.
