Bypass jet engine i.e. counterflow engine, for use in aircraft, has front blower deflecting fresh air around specified degrees in collecting cavity of core engine, where fresh air is sucked in front of outer housing of core engine

摘要

The engine has a core engine (1) whose outer housing (3) is formed with a cavity for a fresh air channel. Fresh air is sucked in front of the housing and drawn behind a front blower (2) and into a collecting cavity of the core engine. 180 degree deflection of the air is made by low and high pressure sections (6, 7) of a compressor and high and low pressure sections (9, 10) of a power turbine under increase of temperature by compression and energy supply in a combustion chamber (8) against flight direction of an aircraft. The blower deflects the air around 90 degrees in the collecting cavity.
