The invention is for a system which provides total cooling for an aircraft airframe which is designed to fly in the speed range of Mach 2 to Mach 8. The system eliminates the necessity of shielding an aircraft airframe constructed of material such as aluminum. Cooling is accomplished by passing a coolant through the aircraft airframe, the coolant acting as a carrier to remove heat from the airframe. The coolant is circulated through a heat pump and a heat exchanger which together extract essentially all of the added heat from the coolant. The heat is tra...
A cooling system for a high speed aircraft comprising: an aircraft; fuel means carried by said aircraft; said aircraft having airframe cooling means; heat pump means comprising evaporator and condenser means for receiving coolant medium from within said airframe cooling means and extracting heat therefrom in said evaporator means; heat exchanger means for receiving fuel from said fuel means and receiving said coolant medium from said evaporator means and transferring heat from said coolant medium to said fuel said condenser means receiving fuel from said...
