水上飞机自由飞模型起飞与降落性能的综合试验

THE COMPREHENSIVE TEST FOR TAKE-OFF AND LANDING CHARACTERISTICS OF FREE FLIGHT MODEL OF A SEAPLANE

本文综述了用4台发动机为动力的水上飞机自由飞模型起飞与降落性能的综合试验,这些性能包括稳定性、操纵性、飞溅、水阻力、着水撞击、起飞砰击、失速及耐波性等。模型与真实飞机保持几何、质量、运动状态、拉力、升降舵效率及其波浪谱的相似,故模型试验与真实飞机的试飞结果比较符合。同时着重介绍了模型试验的机载测试系统与地面测试系统。

The comprehensive test on open water for take-off andlanding characteristics of the seaplane free flight model powered byfour engines is described in this paper.These characteristics consist ofstability,controllability,splash,water drag,landing collision,take-offslamming,stall,seakeeping etc.The model is similar to a full scale sea-plane in the matter of geometry,mass,movement,pull,elevatorefficien-cy and wave spectrum.Therefore,the test results of the model are bas-ically identical with those obtained from the test flight of real sea-plane.Flight and ground measuring systems for the model test are intro-duced emphatically in this paper.
