Problems solved by technology

[0003] When this emergency situation requires a backup power supply, a fan is currently installed at the bottom of the aircraft to generate electricity and store energy for the aircraft. However, since the fan is placed inside the aircraft in advance, the fan will be displayed when it is used, which will undoubtedly change the aerodynamic shape of the aircraft. Extremely unstable, easy to cause the aircraft to lose stability

specific Embodiment approach

[0019] This backup power supply is carried out when the aircraft engine stops for some reason and the APU system fails and makes an forced landing. The specific implementation is as follows:

[0020] 1. Open the front and rear machine covers of the device through the explosive bolt, and the incoming air generated by sliding enters the air inlet.

[0021] 2. The incoming air drives the fan to start the main shaft of the gas turbine, and then ignites the annular combustion chamber to fully burn with the metal nano powder to generate high-temperature and high-pressure gas to drive the turbine to do work.

[0022] 3. At this time, the main shaft of the gas turbine drives the generator, a part of the electric energy is supplied to the aircraft system, and the other part is stored in the battery.

[0023] 4. At the same time, the high-speed rotating fan inhales a large amount of air to fully burn it to produce high-temperature and high-pressure gas that is discharged at high speed ...

Abstract

The invention discloses an aircraft auxiliary power generation mechanism based on the combustion of metal nano powder, which belongs to the technical field of aircraft electrical systems; the invention opens the front cover 15 and the rear cover 16 of the device through an explosion bolt 14, and the incoming flow generated by sliding Air enters the air intake 17; the incoming air drives the fan 1 to start the generator main shaft 10, and then ignites the annular combustion chamber 8 to fully burn with the metal nano-fuel 11 to generate high-temperature and high-pressure gas to drive the turbine 9 to do work; the generator main shaft 10 drives the generator A part of the electric energy is supplied to the aircraft system, and the other part of the electric energy is stored in the storage battery 13; the present invention sucks in more air through the fan to fully burn it with the metal nano powder; the use of the metal nano powder is more active than the general fuel, and the energy generated is relatively low. General fuel is several times higher. Simultaneously, the overall aerodynamic layout of the fuselage is not affected when the device works, which ensures the stability of the aircraft.

Description

technical field [0001] The invention relates to the technical field of aircraft electrical systems, in particular to an aircraft auxiliary power generation mechanism based on metal nano powder combustion. Background technique [0002] With the rapid development of the aviation industry, the aircraft electrical system technology is becoming more and more mature. The aircraft's power demand and electrical system safety are directly related to whether the aircraft can fly safely and effectively. The main power supply of the aircraft is provided by the generator driven by the engine, and usually there are several generators on one engine, so many generators are housed on the engine. The electrical energy produced by one generator is sufficient to meet the needs of the entire aircraft, so when one engine fails, the electrical energy produced by other engines can also maintain the use of electrical equipment on the aircraft. When all the engines fail, the APU system installed at ...
