摘要:
A system and method for reducing aerodynamic drag is disclosed. A compression seal is attached to the inboard edges of the stabilizer and elevators of an airplane. The seal blocks airflow in a gap located between these inboard edges and a fuselage. The shape of the compression seal changes as the shape of the gap changes due to movement of the stabilizer and elevators during flight to effectively block airflow through the gap during flight. By blocking the airflow, the seal reduces the aerodynamic drag of the airplane.

Disclosed is a sinkless electric generator for generating electrical power from temperature cycles encountered by the structure of an aircraft. The sinkless electric generator includes a thermoelectric generator which is in thermal contact with the structure of the aircraft (e.g., the aircraft's skin); an insulated housing containing a thermal mass; and a circuit for providing the energy generated by the thermoelectric generator during the temperature cycles encountered by the structure of the aircraft to a device. The insulated housing is positioned in thermal contact with the thermoelectric generator; wherein during the temperature cycles encountered by the structure of the aircraft, energy is created by the thermoelectric generator when heat is released from the thermal mass contained within the housing through the thermoelectric generator to the aircraft's structure and when heat is supplied from the aircraft's structure through the thermoelectric generator to the thermal mass.
摘要:
An example adjustable linking member (22) of a mounting assembly (20) includes a first attachment portion (24) and a second attachment portion (26). The first attachment portion (24) connects a linking member (22) to a first component (12). The second attachment portion (26) connects the linking member (22) to a second component (14). A variable portion (36) of the adjustable linking member (22) varies a distance between the first attachment portion (24) and the second attachment portion (26) in a first direction when heated. The variable portion (36) varies the distance between the first attachment portion (24) and the second attachment portion (26) in a second direction when cooled. The first direction is opposite the second direction.
摘要:
The invention relates to a cooling system (20) for an aircraft (1) comprising a cooling circuit (21) for transporting a coolant, with the cooling circuit (21) running to a component (22) in the aircraft that is heated up during flying in order to take up heat from the heated-up component via the coolant. The cooling circuit (21) runs to a jet engine (2) for propulsion of the aircraft in order to release heat to a flow of gas (IV) in the jet engine via the coolant.
摘要:
An apparatus (10) and method for surface temperature control is provided. Surface temperature control is achieved by flowing coolant in and then out of a low strength porous layer (18) attached to a structural plenum. An additional layer (24) may be attached to the outer surface of the porous layer (18) to prevent erosion of the porous layer (18) and to facilitate surface film cooling.

System for transpiration coolong of an element in which a substantially non-porous laminate preform (40) is made porous by a pore forming member (34). Coolant (88) is then flown in an area (86) near the surface (84) between the element and the porous laminate. Part of the coolant is transported through the porous member.
摘要:
Le procédé de l'invention consiste à former un corps perméable au gaz (1) comportant des pores (28) ouverts, une première surface (2) destinée à être au contact d'un flux gazeux oxydant (4), susceptible d'oxyder le corps et une seconde surface (6) opposée à la première et à injecter un gaz protecteur (8) exempt d'oxygène à travers la seconde surface (6) entraînant des perturbations dans le matériau lui conférant une protection contre l'oxydation.

An apparatus includes an inlet conduit assembly (80) surrounding a gas flow path (26b) and a combustor (34c) arranged downstream of the inlet conduit assembly. The inlet conduit assembly includes a thermoelectric (TE) device (82) configured to convert heat into electrical energy, a gas flow conduit (80) arranged between the gas flow path and the TE device, and a resilient member (86) configured to bias the TE device into contact with the gas flow conduit.
摘要:
An aero-contoured coating system is provided. The system has an aerodynamically functional coating having at least one or more color layers, one or more first clearcoat layers over the color layer(s) to obtain a pre-aero-contoured coating, the one or more first clearcoat layers configured for abrasion and aero-contouring to obtain an aero-contoured surface, and one or more additional clearcoat layers over the aero-contoured surface. The system further has a structure having a prepared and primed substrate surface with a primer layer. The system further has an aero-contouring device to abrade a plurality of flow surfaces on a pre-aero-contoured coated surface and to mechanically aero-contour a plurality of coating edges to reduce one or more coating edge peaks and coating edge angles of abutting coating edges between the one or more color layers. The system further has one or more masking elements for masking the one or more color layers.
