kinetic and potential energy, inertial force, axial compressorAbstract
It is well-known, that all the fundamental foundations of the modern theory of air-jet engines (AJE) are in full wrong, that generated wrong opinion that in zone H-B2 turbine (engine) energy is not supplied to the gas flow and gas flow pressure up to maximum in zone B2-K is provided only with diffuser (widen) canals between working wheel (WW) blades of low, middle and high pressure compressors (LPC, MPC, HPC) with providing turbine (engine) external work to LPC, MPC, HPC from the back. this in full wrong opinion, which exists during the last 86 years, is simply explained that in LPC, MPC, HPC diffuser (widen) canals are in full not exist because in these compressors only confusor (narrow) canal are existing. In zone H-B2 turbine (engine) provides it¢s energy to the gas flow for widening (vacuum) and acceleration to receive calculated kinetic energy in the cross section B2-B2. In zone of the gas flow pressure B2-K the part of gas flow kinetic energy, which is stored in zone H-B2, which is an external work, which turbine (engine) provides to compressors front the face, is generated into potential pressure energy by means gas flow axial speed decrease from step to step while gas flow braking is provided by pressure leaps, which are generated only on the backs of the blades of WW, and forehead resistant of the last. flow braking generates inertial force, which is directed by the flow and pressure the gas flow to maximum , while that static pressure of gas flow on the backs of the blowing profile blades is much more then the same on trough of the blades, which creates an additional revolve moment for rotor kinetic energy LPC, MPC, HPC keeping.
