Abstract
A multi-layer blanket insulation adapted of use in an aerobrake intended to assist in the return of a space vehicle from a higher earth orbit to a low earth orbit for recovery and possible reuse. Between two face sheets of a cloth material highly resistant to elevated temperatures are interposed a layer of a flexible insulative material and a layer of non-porous foil. The insulation is stitched together into a predetermined pattern. A backside stiffener may be secured to the back face by a layer of a suitable cloth material.
Claims15
A thermal protection system comprising:
- an aerobrake for use to assist in the return of a space vehicle from a geosynchronous earth orbit or higher to a low earth orbit for recovery, servicing and reuse, said aerobrake is subject to be folded from a retracted position to a deployed position where it could be subjected to temperatures equalling 2600.degree. F. on its front face while retaining sufficient flexibility to be refolded to a retracted position;
- and
- a multi-layer blanket insulation attached to said face of said aerobrake, said thermal blanket comprising a first layer of cloth material that is heat resistant to a temperature equalling or exceeding 2500.degree. F., a second layer of cloth material that is heat resistant to elevated temperatures, a layer of flexible insulative material that is positioned between the first and second layers of cloth material, at least one layer of non-porous foil that is also positioned between the first and second layers of cloth material and thread material adapted to withstand elevated temperatures that is used to sew the two layers of cloth, the layer of insulative material, and the non-porous foil together.
