The base of the TY-GPU90 / TY-GPU140 towable aircraft power unit power generation set is installed on the trailer chassis. The cover of the unit is formed by stamping metal sheets, featuring good ventilation, rainproof, and noise reduction capabilities. The appearance is smooth and it has a large cover hatch for the convenience of maintenance personnel to carry out maintenance on the unit. This vehicle consists of: engine, generator, voltage regulation system, frequency protection system, voltage protection system, load protection system, output control system, operating system, output system, and trailer chassis, etc. The power unit adopts an intelligent integrated ECU control system, and the unit takes noise reduction measures. The noise level is no more than 85 decibels at a distance of 1 meter from the unit.
This power unit meets the power supply requirements for airborne electrical equipment of 400Hz AC/DC types. The power unit has a complete protection and dynamic regulation system, which can meet the stability requirements of aircraft using intermediate-frequency power sources for frequency and voltage. The power unit can work all day long, has good rainproof, waterproof, moisture-proof, and anti-corrosion functions, and has a rainproof device for the cable plug.
