中文摘要:
      为满足直升机部队计算机辅助决策、作战模拟推演等工作需要,用基本的直升机悬停性能和少量的原始数据作支持,对旋翼功率及其拉力计算方法进行建模。通过分析直升机动力学特点,运用动量法和叶素理论,将直升机旋翼功率进行拆分求解,推导出一套旋翼需用功率及可用功率的简化计算方法;根据线性外插法,用剩余功率建立拉力计算模型,对旋翼拉力进行估算。最后通过算例说明简化计算模型的可行性,解决了确定直升机飞行性能和动力学仿真的实际需要,具有较强的实用价值。
英文摘要:
      To fulfill the need of computer assistant decision-making and simulating battle drilling, based on the basic helicopter spot performance and a few of original data, the paper makes a model of the Algorithm of rotor's power. By analyzing the characteristics of dynamics and using the momentum theory and blade theory, a computational method of helicopter rotor power and available power is deduced. The rotor power will be respectively calculated as several parts. The pull's calculation model is established with the remnant power by using the linear outer insert method. Finally,a calculated example proves the feasibility of the simplified arithmetic model,thus the problems of flight performance assurance and dynamics simulation are solved.This algorithm is of applied importance.
