MOVABLE AIRFIELD MAINTENANCE PLANT Russian patent published in 2009 - IPC B64F1/34 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to airfield equipment designed to start aircraft gas turbine engines. Proposed plant comprises all-metal three-section body mounted on wheeled chassis with hitchbar swinging upward. Hitchbar fixed link accommodates roller support swinging downward. One section of the body houses gas turbine engine with starter, current generator and compressor. Central section is separated by partition into two compartments, one accommodating fuel tank and another housing hydraulic station. Control board of the latter is mounted on its top. Hydraulic pressure and suction lines are connected to aforesaid control board, on one side, and on the other, to aircraft hydraulic system. Third section houses current rectifier, storage batteries and air conditioner. Note that T-joint is connected to bypass valve first outlet. Flexible hose is connected to one of T-joint outlets to feed hot air for starting aircraft gas turbine engine. Air hose to feed hot air into air conditioner is connected to the other outlet of the said T-joint, both hoses are furnished with shut-off valves controlled from the said control board. Note also that the second flexible hose is connected to air conditioner outlet to feed warmed air into passenger compartment and/or pilot cab.
