Jet Engines and Their Lubrication
Journal of the Fuel Society of Japan, 1953 ジエット・エンジンの動作機構を説明し, 各回転部の荷重を考察してこれに要する潤滑方法について述べた。潤滑油の性状も往復エンジンとちがつた特色を持つ必要がある。-60°～260℃の広範囲にわたつて安定な性質を持つ粘度指数の高い油が要求されるわけで, 、米軍規格を主として実用潤滑油の規格を説明した。つぎに米国におけるジエット・エンジン用潤滑油の研究製造について, 硅素樹脂潤滑剤, 石油系潤滑油, 合成潤滑油, グリース, 添加剤などの現状特質について述べている。

Active Jet Noise Control of Turbofan Engine Based on Explicit Model Predictive Control
Applied Sciences, 2022 The active jet noise control received significant attention due to the little influence it has on the engine performance. The active jet noise control is a multivariable problem because it needs to achieve the simultaneous closed-loop control of jet ...

Simple Thermodynamics of Jet Engines [PDF]
American Journal of Physics, 2010 We use the first and second laws of thermodynamics to analyze the behavior of an ideal jet engine. Simple analytical expressions for the thermal efficiency, the overall efficiency, and the reduced thrust are derived. We show that the thermal efficiency depends only on the compression ratio r and on the velocity of the aircraft.
