本文导出了螺旋桨驱动的轻于空气飞行器和推力翼轻于空气飞行器所需的光功率与飞行器质量和光速度的经验关系式。旋翼飞行器的关系式包括旋翼直径作为附加参数。对于飞艇、飞机和无人机，这些关系的功率分别跨越约6 - 7个数量级，包括模型飞机和无人驾驶飞行器，以及传统的载人飞行器。从第一原理出发，这些关系式被推广到其它环境（不同的重力和大气密度），并允许在这个世界和其它世界上对飞机方案进行快速和方便的初步评估。结果与陆地鸟类和潜艇相比毫不逊色。
Empirical relations for the required e ight power of propeller-driven lighter-than-air and e xed-wing heavierthan-air vehicles are developed purely as a function of vehicle mass and e ight speed. A relation for rotary-wing vehiclesincludes rotordiameterasan additional parameter. Forairships,airplanes, and helicopterstheserelations each span some 6 ‐7 orders of magnitude in power, covering model aircraft and unmanned air vehicles, as well as conventional crewed vehicles. From e rst principles, these relations are extended to other environments (different gravity and atmospheric density ) and allow the rapid and convenient preliminary evaluation of aircraft concepts on this world and others. Results compare favorably with terrestrial birds and submarines.
