摘要:

能量平衡是太阳能飞机设计工作的核心和难点。基于太阳能飞机能量原理,结合太阳辐射模型和太阳能飞机典型飞行剖面开展太阳能飞机能量平衡建模研究。根据太阳能飞机起飞-爬升-巡航阶段和持续跨昼夜飞行阶段的飞行剖面和能量需求,分别建立了各阶段的能量平衡模型,给出了各时段的能量特性计算方法并对傍晚下滑阶段的多种飞行情况进行了分类讨论。最后以某太阳能飞机为例对本文所建立的起飞-爬升-巡航能量平衡模型和持续跨昼夜飞行能量平衡模型进行了验证。

Abstract:

Energy balance is the core factor and also one of the most difficult points of the design of solar powered aircrafts. Based on solar radiation model, energy principle and typical flight profile of solar powered aircrafts, this paper conducts research on energy balance modeling for solar powered aircrafts. Both takeoff-climb-cruise energy balance model and the whole day duration flight energy balance model are constructed based on the flight profile and energy requirement. Energy calculating formula for each time phase is presented, and multiple cases of glide are discussed. The energy balance models are validated through an analysis example.

Key words: solar powered aircraft, energy balance, model, whole day duration flight, flight profile
