Thermal protection device, in particular for an aerospace vehicle
First Claim
1. A thermal protection device, in particular for an aircraft or a space vehicle, the device comprising a plurality of juxtaposed unit modules each comprising a fairing element provided with fixing tabs, thermal insulation integrated in the fairing elements, and rigid connection means for releasably connecting the fixing tabs to a primary structure that is to be protected,wherein the gap between neighboring fairing elements is limited to a value substantially equal to the minimum value necessary for accommodating thermal expansion of the fairing elements, and the rigid connection means for connecting a fixing tab of a module to the primary structure comprise a ball fixed to the fixing tabs in adjustable manner and capable of being locked inside a corresponding socket of a retaining part fixed to the primary structure, the ball being locked in its socket by means of a bolt capable of being released by action exerted against a resilient return force.

Abstract
The thermal protection device is made up of a plurality of juxtaposed unit modules each comprising a fairing element provided with fixing tabs and thermal insulation integrated in the fairing element. The gap between neighboring fairing elements is limited to the minimum width necessary for accommodating thermal expansion thereof. The connection means which releasably connect the fixing tab to a primary structure to be protected comprise a ball fixed to the fixing tab in adjustable manner and capable of being locked in a corresponding socket of a retaining part fixed to the primary structure. The ball is locked in its socket by means of a bolt capable of being released by action exerted against a resilient return force.
