The atmospheric hypersonic flight of sub-orbital and space vehicles generates aerodynamic heating and high wall heat fluxes, inducing high temperatures on the vehicle’s structures and affecting their mechanical behavior, besides degrading the operation of board equipment. Furthermore, since payload preservation is always mandatory, the use of effic...

... A cork layer with 1 mm thickness was included in the TISSC design, in order to avoid the external temperature of the structure overpasses the maximum limit allowed, as recommended in the previous work of ( Damilano et al., 2015). In order to perform a straight comparison with the conventional TPS, an equivalent unitary cell was also created for this system, showed in Fig. 11. ...

Space and suborbital vehicles reach high speeds while flying in the atmosphere, which results in aerodynamic heating and structural loads due the dynamic pressure on the surface. High resistance materials are employed to support such requirements, increasing the spacecraft weight and launching costs. The use of an integrated thermal structural protection (TISSC) was proposed, in order to improve the overall performance, resulting in a significant reduction in weight and cost and increasing the life cycle of the vehicle. This work is aimed in analyzing the economic viability of these structures, applied to the SARA suborbital platform, which is being developed by IAE (Institute of Aeronautics and Space) for experiments in micro-gravity environment. Possible combinations of materials to be employed, including their cost and manufacturability, were analyzed, concluding that the use of this system represents an advantage when compared to the conventional thermal protection system.
... To operate safely, several computational and experimental studies have been conducted that are aimed at understanding SARA's aerothermodynamics [18][19][20][21][22][23][24][25][26][27][28][29][30]. However, these previous studies have provided very little understanding of the impact of chemical reactions on the SARA capsule during the reentry phase. ...
