Abstract
A perforated heat shield (20) is formed of a single layer and is implemented to be positioned between an aircraft brake assembly (34) and wheel assembly (28) in order to effectively protect the wheel assembly (28) and adjacent components from excessive thermal energy generated by an operation of the brake assembly (34) and to promote the cooling of the brake assembly (34) by allowing a partial amount of the thermal energy to radiate to the wheel assembly (28) through apertures (22) provided in the heat shield (20).
Claims20
A heat shield and an aircraft landing gear that includes a wheel assembly having a wheel and a wheel tubewell and a brake assembly having stators and rotors alternating along a length direction of a wheel assembly axle,
- the heat shield being formed of a single layer and being provided with a plurality of apertures formed across a surface thereof, along said length direction, thereby creating a pattern of direct line-of-sight regions from said alternating stators and rotors to said wheel assembly for allowing direct thermal radiation from the alternating stators and rotors to the wheel assembly,
- wherein said heat shield is dimensioned and shaped for positioning between the alternating stators and rotors and the wheel assembly of the aircraft.
An aircraft landing gear comprising:
- a wheel assembly having a wheel and a wheel tubewell;
- a brake assembly including a brake stack that has alternating stators and rotors, the brake assembly being attached to the wheel assembly and an axle of the aircraft landing gear, said stators and rotors alternating along a length direction of said axle;
- and
- a heat shield being provided between the wheel assembly and the brake assembly, the heat shield having a plurality of apertures formed across a surface thereof, along said length direction, thereby creating a pattern along said length direction of direct line-of-sight regions from said alternating stators and rotors to said wheel assembly for allowing direct thermal radiation from the alternating stators and rotors to said wheel assembly.
