中文摘要: 斜切喷管常用于产生反向推力,或产生旋转力矩使火箭高速旋转的涡轮式火箭发动机中.以拉瓦尔喷管斜切结构为基本模型,用压力积分法推导了斜切喷管的推力、推力偏转角和力矩的公式,并论证了斜切角和扩张半角对上述参数的影响,从而为斜切喷管的设计提供了理论基础.
Abstract:The scarfed nozzle is used in engines which can produce reversal thrust, or to produce revolving torque on turbine rocket engines at high speed.Researching for the laval scarfed nozzle, the theoretical calculation on thrusts and their coefficients, thrust angle, torque for the model are made, and their theoretical equations and their dimensionless values with different ψ and θ are achieved.These conclusions with analyses and comparisons will benefit the research on the performance calculations of scarfed nozzle and its initial theoretical design.
