The present disclosure provides an airplane ground deicing installation that minimizes the impact of deicing operations on the airport during icing conditions. The installation does not require alteration of a normal taxi pattern and can be performed as quickly as the average separation time between take-offs. The installation allows modification of its shape to adapt to the contour of almost all types of commercial passengers airplanes operating from major airports, and simultaneously deices large surfaces of the airplane. Deicing and anti-icing fluids are applied to airplane surfaces from nozzles positioned in close proximity to the airplane's surface. Speed and adaptability to different types of airplanes, combined with a design that allows rapid relocation of the installation, are key features that make it possible to place the installation on the taxiway, close to the head of the runway it serves, such that the taxi pattern and the separation in between takeoffs are not altered as compared to the normal operations of the airport.

An aircraft wing incorporating a coolant loop through which a coolant flows. The coolant loop is a closed loop and a part of the closed loop is formed within a body of the aircraft wing. Aircraft and other systems are also disclosed as well a parts that can be cooled.

Systems and methods of deicing aircraft propellers include a deicing heater timing cycle, i.e. heater on/heater off schedule that is calculated as a function of ambient temperature and the airspeed of the aircraft.

A two-phase type heat transfer device (10) for heat sources operating at a wide temperature range. The heat transfer device (10) includes an evaporator (21) collecting heat from a heat source, a condenser (21) providing heat to a cold sink by a first working fluid passing through liquid and vapor transport lines (25, 27) that connect the evaporator (21) and the condenser (23). The evaporator (21) is arranged inside a saddle (31) configured for avoiding that the temperature of the first working fluid in the evaporator (21) is greater than its critical point. The invention also refers to aircraft ice protection systems using the heat transfer device (10).

A connecting arrangement for joining at least two components to form a structural assembly, near a wing of an aircraft, wherein at least one component is formed from a fiber composite plastic and at least one further component is formed from either a metal or a fiber composite plastic. A bushing is secured in a hole through the components. The bushing includes a first end with a collar which faces towards a lower face of the structural assembly and a second end. A zone of an upper face of the structural assembly radially surrounds the second end and includes a depression. A connecting element is installed in the bushing. This provides a smooth, aerodynamically beneficial configuration of the upper face, which can be coated, and which ensures a reliable electrical contact between the connecting element and a conductive surface of the first component.

Embodiments of the present disclosure provide systems and methods for averting, shedding, or otherwise managing ice accretions that may develop during flight of an aircraft. Example systems and methods direct oil from a lubrication and cooling path to targeted sections of ice-prone surfaces to manage ice accretion in a way that does not unduly increase the total volume of oil, require larger pumps, or complicate the system.
