海鸥300模型起飞滑行性能估算技术研究

Estimated Research on the Performance of HO300 Scaled Model's Takeoff and Taxiing

海鸥300飞机模型采用发动机机背高置布局,模型在起飞滑行时发动机推力会产生一个很大的低头力矩,影响模型的飞行操纵。本文主要介绍螺旋桨的风洞试验结果特殊处理方法、模型滑行起飞所需功率的估算方法以及用升降舵消除发动机产生低头力矩的估算方法,通过滑行试验与仿真结果对比,验证了该估算方法的有效性、正确性。

For the engine high-layout on the topside of HO300 scaled model’s fuselage, the engine will generate a large pitch-down moment which affects the model’s maneuverability. In this paper, one special data-processing method was described for the data of propeller wind tunnel test at ifrst. Then, the method of the power estimation for the model’s takeoff and taxiing was introduced, and the estimation method was discussed which was used for eliminating for the moment of pitch-down produced by engine. Finally, one real flight test was presented and the result contrasted with simulation shows the good validity and correctness of the proposed methods.
