Umbrella-shaped boosting solar aircraft

Abstract

The invention provides an umbrella-shaped boosting solar aircraft. The aircraft comprises an aircraft body, a rocket engine, a solar film, a coaxial double-rotor mechanism, an energy storage battery and an umbrella-shaped retractable structure; the coaxial double-rotor mechanism is installed at the upper end of the aircraft body, the rocket engine is installed at the lower end of the aircraft body, the umbrella-shaped retractable structure is installed outside the middle section, and the energy storage battery is installed inside the aircraft body; the umbrella-shaped retractable structure isclung to the outer wall of the aircraft body when being folded, is conical when being unfolded and is coaxial with the aircraft body; and the solar film covers the upper surface of the umbrella-shapedretractable structure and supplies power to the energy storage battery. The launching initial speed can be increased, the initial loss energy is reduced, the variable structure design of the aircraftis realized, and the aircraft is more convenient to launch, recover and store.

Description

technical field [0001] The invention relates to a solar-powered aircraft and belongs to the technical field of testing and testing. . Background technique [0002] Solar aircraft technology has broad application prospects, such as aerial fixed-point observation, reconnaissance, early warning, interceptors, high-altitude radar stations, communication relays, border patrols, electronic warfare, battlefield monitoring, atmospheric satellites, environmental and disaster monitoring, and even anti- Guide and so on. [0003] At present, the aircraft used for reconnaissance and observation mainly include helicopters, airships, etc., such as UAVs with conventional layouts, high-altitude balloons, airships, and conventional UAV systems. They have their own advantages, but most of these aircraft rely on fossil fuels As the main source of power, it is capable of performing short-distance, short-range and low-altitude missions with ease, but in the face of higher mission requirements, ...

Problems solved by technology

[0003] At present, the aircraft used for reconnaissance and observation mainly include helicopters, airships, etc., such as UAVs with conventional layouts, high-altitude balloons, airships, and conventional UAV systems. They have their own advantages, but most of these aircraft rely on fossil fuels As the main source of power, it is capable of performing short-distance, short-range and low-altitude missions with ease, but in the face of higher mission requirements, such as ultra-long air time, ultra-long flight distance, etc., due to the long-term stable and efficient energy supply conditions Constrained by traditional aircraft, it seems powerless

In order to solve the above problems, in the last century, many domestic and foreign scientists began to study solar aircraft, and related technologies have achieved remarkable results, such as the "Sun Challenger" and "Helios" aircraft developed by the United States, and the "Sun God" aircraft developed by the United Kingdom. "Western Wind 3" aircraft, etc. Domestic representatives include "Soarer" aircraft, "Green Pioneer" aircraft, etc., but limited by the conversion efficiency of photovoltaic cells, in order to obtain a larger lighting area, the existing solar aircraft still use large Aspect ratio structure, which directly leads to increased flexibility and insufficient rigidity of the aircraft structure, which seriously affects the flight safety of the aircraft

In order to fundamentally solve the problems of low structural rigidity, bulky volume, inconvenient storage, recovery and launch of solar-powered aircraft, as well as the low efficiency of response to emergencies and emergencies, there is an urgent need for a solar-powered aircraft that can meet the needs of Requirements such as rapidity and convenient recycling
