Title: Vehicle
Inventor: ZAHRADNIK JIRI
IPC: B64F5/20
Filed: 1984-04-03
Abstract: The invention relates to a vehicle, especially a de-icing vehicle for aircraft, and a central energy supply system specially intended for vehicles of this type. Whereas the trend with these vehicles has hitherto been towards separate drive assemblies for the supply of different types of energy such as vehicle propulsion, heating demand, electrical current demand, the central energy supply system proceeds from a single main assembly, especially a gas turbine, which meets the entire, widely varying energy demand of the vehicle. Since special vehicles generally only have special spheres of application the approach adopted in the vehicle according to the invention is to extend the working range by means of rapidly interchangeable pay load pallets and to reduce considerably the preparation times for the entire system.
