不间断飞行太阳能飞机是以太阳能作为飞行动力并能储存白天采集的太阳能完成越夜飞行的飞机,这种飞机力求通过减少、减免起降和补给维护来降低全寿命周期使用成本。建立了由“建立能量链”、“建立质能关系”和“连接总质量和能量链起点完成迭代环”三步组成的不间断飞行太阳能飞机总体参数设计的一般方法。为了减少常数化的升力系数和零升阻力系数在布局的气动潜力上造成的浪费,推导了用于耦合与不间断飞行能力相关的布局参数的升力系数和零升阻力系数估算模型,并对上述方法加以改善。以“Skysailor”作为实例考察新方法的应用效果,结果表明:新方法拓展了设计域、增强了设计方案的负载能力。
Uninterrupted flight Solar powered aircraft are solar powered aircraft that can store solar energy collected during the day to complete an overnight flight. The aircraft seeks to reduce life-cycle cost by reducing, reducing take-off and landing and maintenance. Established a general method of designing the overall parameters of an uninterrupted flight solar aircraft consisting of three steps: “establishing energy chain ”, “establishing the relationship of mass energy ” and “connecting the starting point of total mass and energy chain to complete the iteration loop ”. In order to reduce the waste caused by the constant lift coefficient and the zero lift coefficient on the aerodynamic potential of the layout, the lift coefficient and the zero lift coefficient estimation model for coupling the layout parameters related to the uninterrupted flight capability are deduced. Method to be improved. Taking “Skysailor” as an example to examine the application effect of the new method, the results show that the new method expands the design domain and enhances the load capacity of the design scheme.
