1. A reusable thermal protection device that can be fitted onto aircraft and facilities subject to high levels of heating and loads due to the environment such as aeronautic or space aircraft, comprising : - a plurality of adjacent panels (12) making up a continuous, smooth surface defining the contour of the aircraft (3), serving as a shield against the outside environment and locally subject to stress and environmental loads - attachment means (13) for said adjacent panels (12) - an insulating layer (15) located between said adjacent panels (12) and the aircraft (3) so as to preserve the latter against excessive heating as well as attachment means for said insulating layer (15) onto the aircraft (3) characterized in that, in addition, it consists of : - connection means (18) linking said adjacent panels (12), - watertightness means for the aircraft (3) relative to the outside environment, made up of watertight junctions (14) between adjacent panels (12) and watertight parts fitted to the attachment means (13) of said panels (12), as well as connection means (18) between adjacent panels (12), the latter watertightness means preventing the exchange of gas and fluids through the outer surface of the aircraft (3), - a thin, watertight sheet (16) equipped with watertight bulkheads (17), located between the panels (12) and the aircraft (3) or between the adjacent panels (12), used when the watertightness provided by the watertight junctions (14) and the watertight parts (48, 55) has to be improved or when redundant watertight connections (14) are needed or when it is advantageous to trap a layer of air between said sheet (16) and the panels (12), said sheet (16) leading to no transfer of mechanical stress between the components of the stress-bearing structure (80) of the aircraft (3) or between the panels (12) and said stress-bearing structure (80), in that the device is directly attached to the stress-bearing structure (80) of the aircraft (3) obviating the need for an intermediate structure wall close to said device, such as the fuselage wall of the aircraft (3) to be used as support for this device or as a watertight barrier between the aircraft (3) and the outside environment, in that the adjacent panels (12) are watertight, flat or curved and feature good resilience properties, in that those elements of said device that are subject to high temperatures, including the seals, are made of refractory materials featuring good resilience properties even at these temperatures and lend themselves to the manufacture of light and resilient parts, in that this device is easily repairable using makeshift panels (91).
