发动机推重比(Thrust to Weight Ratio,简称TWR),是指发动机产生的推力与飞机总重量之比。某种程度上,其反映了一个飞机的性能水平。TWR越大,飞机越具有优秀的爬升性能和机动能力。通常,TWR大于1的飞机能够垂直起降或近似于垂直起降,TWR小于1的飞机在起飞时需要一定的起飞滑跑距离。 二、影响因素 发动机推重比的值取决...
发动机推力比(Thrust-to-Weight Ratio)是指飞机引擎产生的推力与飞机自身重量的比值,是一个关键的指标,影响着飞机的起飞性能和燃油消耗。推力比越大,飞机的加速和爬升能力就越强,起飞距离也就越短;反之,推力比越小,起飞距离就越长。 二、如何计算发动机推力比? 发动机产生的推力可以通过静推力试验来确定。而飞机...
