The invention provides a low-cost recoverable rocket type test aircraft which is used for realizing flight test verification of various carrier rocket recovery algorithms and carrier rocket intelligent control algorithms. The aircraft is simple and firm in structural design and easy to modify, and stable landing control can be achieved when the rocket falls by adopting the thrust-adjustable aviation turbojet engine. The aircraft can realize all six-degree-of-freedom position and attitude movement through the power system and the execution mechanism. A control system of the aircraft is high in computing power, and carrying of a medium-scale deep learning algorithm IP core and carrying tests of a multi-core parallel algorithm can be achieved through cooperation of a rocket-borne flight control machine and a data processing computer with high computing power. A fault-tolerant guidance law is arranged in the aircraft flight control software, and when an aircraft test algorithm is out of control, the fault-tolerant guidance law can be switched to realize safe flight of the aircraft. Meanwhile, the emergency recovery device at the head of the aircraft can ensure safe landing of the aircraft when the executing mechanism fails.

    本发明提出了一种低成本的可回收火箭型试验飞行器,用于实现各类运载火箭回收算法、运载火箭智能控制算法的飞行试验验证。飞行器自身结构设计简单坚固易修改,采用推力可调节的航空涡喷发动机可实现火箭下落时的稳定着陆控制。飞行器通过动力系统和执行机构可实现全部六自由度的位置及姿态运动。飞行器配备的控制系统算力较强,通过箭载飞控机与算力强大的数据处理计算机配合,可实现中等规模深度学习算法IP核的搭载和多核并行算法的搭载试验。飞行器飞控软件内部设有容错制导律,可在飞行器试验算法失控时,可切换至容错制导律实现飞行器安全飞行。同时,飞行器头部的应急回收装置可保证执行机构失效时飞行器的安全着陆。
