High altitude air start equipment for aircraft reciprocating engine

A high altitude air start equipment for an aircraft reciprocating engine, comprising:

• a compressor configured to suck and compress air, and supply the compressed air to the aircraft reciprocating engine;
• a motor configured to supply the compressed air to the reciprocating engine to restart the reciprocating engine or to restore output by outputting rotational power to the compressor when the reciprocating engine stops or malfunctions during flight of the aircraft;
• a valve configured to switch between supplying air compressed by the compressor to the reciprocating engine and supplying air uncompressed by the compressor to the reciprocating engine;
• and
• a controller configured, when the reciprocating engine stops or malfunctions during flight of the aircraft, to automatically drive the motor, and to automatically switch the valve so that the air compressed by the compressor is supplied to the reciprocating engine,
• an air box disposed between the compressor and the reciprocating engine, the air box being configured to mitigate pressure fluctuations of the compressed air supplied from the compressor to the reciprocating engine,
• wherein a capacity of the compressor is determined to be a capacity capable of supplying the compressed air to the reciprocating engine at a pressure within a pressure range of air required for restarting the reciprocating engine during flight of the aircraft,
• wherein a size of the air box is determined such that the compressed air supplied to the reciprocating engine to restart the reciprocating engine during flight of the aircraft is at the pressure within the pressure range.
