Abstract
An aircraft brake assembly incorporating components which are sensitive to heat and to contact with substances present in runway,.e.g., de-icer compositions and cleansing liquids. The assembly includes an external member to shield the components from the liquids. The external member may comprise a rigid or flexible, fluid-impermeable or porous material located to receive and retain the liquids. Heat generated through the use of the brake assembly may evaporate any liquid settled on the external member or at least discourage any liquid from settling thereon.
Claims29
An aircraft brake assembly incorporating a heat stack which is sensitive to heat and to contact with substances present in runway de-icer compositions and cleansing liquids, the heat stack having an end, the assembly comprising shielding means formed of a porous material mounted on an exterior surface of the heat stack at the end of the stack to receive and retain, in use, impinging said compositions and liquids, within the pores of said porous material, to which the heat stack is sensitive.
An aircraft brake assembly incorporating components which are sensitive to heat and to contact with substances present in runway de-icer compositions and cleansing fluids, the assembly including external means to shield the components from the liquids, said shielding means comprising a porous material through which air is flowable to cool the components, the porous material being located to receive and retain said compositions and liquids, within the pores of said porous material, in use.
A method of shielding the components of an aircraft brake assembly which are sensitive to heat and to contact with substances present in runway de-icer compositions, and cleansing liquids, the brake assembly having an outside, the method comprising providing shielding means comprising a porous member, mounting the shielding means on the outside of the assembly in a manner which will not substantially increase the temperature of the heat sensitive components and, when in use, enables receiving and retaining said compositions and liquids, within the pores of said porous material.
A method of shielding the components of an aircraft brake assembly which are sensitive to heat and to contact with substances present in runway de-icer compositions, and cleansing liquids, the brake assembly having a heat stack with an exterior surface having an end, the method comprising:
- providing shielding means comprising a porous member having pores, mounting the shielding means on the exterior surface of the end of the heat stack in a manner which will not substantially increase the temperature of the heat sensitive components and, when in use, receiving and retaining said compositions and liquids within the pores of the porous member.
An aircraft brake assembly incorporating a heat stack which is sensitive to heat and to contact with substances present in runway de-icer compositions and cleansing liquids, the heat stack having an end, the assembly comprising shielding means mounted on an exterior surface of the heat stack at the end of the stack and including plural open spaces through which air is flowable to cool the heat stack and to receive and retain, in use, impinging said compositions and liquids within the open spaces of said shielding means to which the heat stack is sensitive.
