| Jul 27 at 1:12 | comment | added | Level River St | Flow isn't the primary reason for the high pressure and low pressure parts of the engine rotating in opposite directions Each row of rotating blades is followed by a row of stationary blades so direction of rotation of different sections doesn't matter much for flow. The main reason to reduce the gyroscope effect of the engine, which would otherwise interfere with control inputs (for example exerting a pitch torque when the pilot turns the aircraft in yaw.) To a lesser extent, power changes could exert a roll torque on the aircraft if the different sections didn;t rotate in opposite directions | |

Generally military engines will have different needs for efficiency, reliability, maintainability, maximum power, cruising speeds etc. than the engines used on civil aircraft. The engines on a military transport aircraft are comparable to those on civil airlines. The engines on a fighter jet are totally different, and so are those on cruise missiles. | |
