A device for deicing a wall of an aircraft, comprising a closed circuit. The closed circuit comprises at least one condenser, positioned in the environment of the wall that is to be deiced, and in which a heat-transfer fluid condenses, generating energy in the form of latent heat which is transmitted to the wall that is to be deiced, at least one evaporator positioned in the environment of a heat source sited remotely with respect to the wall, and in which the heat-transfer fluid evaporates, absorbing energy in the form of latent heat coming from the heat source. At least part of the closed circuit is facing, in contact with, or positioned in, the wall that is to be deiced, being made of a material transparent to electromagnetic fields.

An aerospace plane having an elongate body supporting a pair of wings each having at least two angled, trailing edge portions. The pair of wings are adapted to extend away from the elongated body in opposing directions. A landing gear assembly is operatively associated with the elongated body to be moveable from a retracted position where the landing gear assembly is substantially locatable within the elongated body and an extended position where the landing gear assembly extends at least partially away from the elongated body. At least one engine adapted to generate thrust. At least one stabilizer adapted to assist with movement of the aerospace plane during flight. The at least one engine is located at least partially within an intake housing adapted to direct air into said at least one engine. The intake housing having at least one inlet door adapted to move from a fully open position, which allows air to pass into the engine, to a sealingly closed position which prevents air from flowing into the engine, when the engine is shut down during flight.

An icing protection system comprises a fuel cell, an evaporative cooling system, a thermal deicing device, a control unit and a device for measuring the pressure in the evaporative cooling system. The evaporative cooling system is in thermal contact with the fuel cell and with the thermal deicing device in order to conduct heat from the fuel cell to the thermal deicing device. The control unit controls the electrical power demanded from the evaporatively cooled fuel cell in dependence on a deviation of the pressure measured by the pressure measuring device from a predetermined NOMINAL pressure. In this way, an energetically very efficient and very well controllable icing protection system is made available that can be operated without bleed air supplied by engines or electrical energy provided by engine generators.

Systems and methods for providing rain and ice removal on a windshield are. provided. The system may be implemented on a vehicle, such as an aircraft. In one embodiment, a system includes an injection molded windshield and a frame coupled to the injection-molded windshield and to the vehicle. The frame includes a channel that directs at least one of air or fluid onto an exterior surface of the windshield. The frame includes one or more one-way check valves. A fluid pump pumps fluid through the channel and onto the windshield. A reservoir stores de-icing fluid that is retrieved by the fluid pump. Air sources pump air through the channel and onto the one or more windshields. A controlling device controls the fluid pump or the air sources.

A deicing fluid recovery system for aircraft deicing apparatus includes a storage tank from which a deicing fluid/water deicing mixture is pumped through a line heater to a deicing fluid distribution and collection zone for application to the wings and fuselage of aircraft. Expended deicing fluid is collected in a drainage system incorporated into a concrete or asphalt pad and directed to a sump. Upon accumulation of a sufficient quantity, the diluted used deicing fluid is pumped to a sludge tank. Solids and free water are separated by settling and filtration processes in the sludge tank. The filtered deicing fluid mixture is heated through sequential heat exchangers and directed to a regenerator. The deicing fluid mixture is leaned by a dehydration process in the regenerator in which the mixture is heated and compressed air is injected to exhaust water from a stripping column. The lean deicing fluid flows over an overflow weir into an accumulator. The heated and leaned deicing fluid mixture then is passed back through the sequential heat exchangers, as a heat source, and pumped back into the storage tank for subsequent reuse.
