Technical specification of ground air source group for towed aircraft

Technical specification of ground air source group for towed aircraft

Aircraft starting air source car is mainly composed of towed chassis, chassis frame, unit, gas supply assembly (including gas path control system, etc.), cover shell, hose groove, electrical system, etc. The car is designed with rear air compressor and radiator (for air compressor), middle diesel engine (Cummins M15) and air filter, front cooling fan and muffler. Diesel-driven air compressor compression system and radiator drive, diesel-driven air compressor compression system can efficiently and conveniently output low-pressure, high-flow compressed air for aircraft engines, and auxiliary gas supply for aircraft inspection or air conditioning. Gas supply flow ≥300PPM, auxiliary gas supply :1.7-2.1bar(25-30psi), adjustable; Starting gas supply :2.4-2.9bar(35-42psi)
