The ARMOR TPS is one of important candidate structure of RLV. It will be the best selection for all kinds of RLV. So the ARMOR thermal protection system will be used in aviation and spaceflight field more and more widely. ARMOR TPS panel is above the whole ARMOR TPS, and the metal honeycomb sandwich structure is the
surface of the ARMOR TPS panel. So the metal honeycomb sandwich structure plays an important role in the ARMOR TPS, while it bears the flight dynamic pressure and stands against the flight dynamic calefaction and impact load. The metal honeycomb sandwich structure is made of upper faceplate, lower faceplate and honeycomb core.
In the course of the reusable launch vehicle working, it is possible that the space chips impact its outer surface. The main problem is what impact the metal honeycomb sandwich structure can stand and how many times it can stand. In the high speed impact experiment we choose different quality and velocity to simulate real space
environment. This paper will analyze the mechanics behaviour of metal honeycomb sandwich structure in the course of impact, and then we make sure the limit impact load and get the effect of impact flaw.
Thermal protection system is one of the key technologies of reusable launch vehicle (RLV). The ARMOR TPS is one of
important candidate structure of RLV. ARMOR TPS has many advantages, for example: fixing easily, longer life, good
properties, short time of maintenance and service. In comparison with traditional TPS, the ARMOR TPS will be the best
selection for all kinds of RLV. So the ARMOR thermal protection system will be used in aviation and spaceflight field
more and more widely because of its much better performance. ARMOR TPS panel is above the whole ARMOR TPS,
and the metal honeycomb sandwich structure is the surface of the ARMOR TPS panel. So the metal honeycomb
sandwich structure plays an important role in the ARMOR TPS, while it bears the flight dynamic pressure and stands
against the flight dynamic calefaction. Because the active environment of metal honeycomb sandwich structure is very
formidable, it can produce interface connection defects which can exist in the process of manufacture as well. Tensile
mechanical properties of the metallic honeycomb sandwich structure with defects are analyzed to obtain damage
tolerance of the structure. The effect of shape, dimension and location of defects on the tensile mechanical properties is
conducted by experimental study. Then finite element analysis is performed to validate the experimental results.
Haynes214 which is a kind of super alloy materials with high performances is chosen as both face sheet and core in this
paper.
Thermal protection system is one of the key technology of reusable launch vehicle (RLV). After C/C and ceramic-matrix
composite used in space orbiter, one new-typed thermal protection systems (TPS)-ARMOR TPS is coming forth.
ARMOR TPS is means adaptable, robust, metallic, operable, reusable TPS. The ARMOR TPS has many advantages, for
example: fixing easily, longer life, good properties, short time of maintenance and service. The ARMOR TPS is one of
important candidate structure of RLV. ARMOR thermal protection system in foreign countries for reusable launch
vehicle is used instead of the traditional ceramic-matrix composite thermal protection system and C/C thermal protection
system. Also the constituent feature of ARMOR thermal protection system is much better than the traditional TPS. In
comparison with traditional TPS, the ARMOR TPS will be the best selection for all kinds of RLV. So the ARMOR
thermal protection system will be used in aviation and spaceflight field more and more widely because of its much better
performance. ARMOR TPS panel is above the whole ARMOR TPS, and the metal honeycomb sandwich structure is the
surface of the ARMOR TPS panel. So the metal honeycomb sandwich structure plays an important role in the ARMOR
TPS, while it bears the flight dynamic pressure and stands against the flight dynamic calefaction. The metal honeycomb
sandwich structure is made using the technique of the whole braze welding. In the course of the vacuum high
temperature braze welding, its surface will appear concave. The reasons which lead to the shortage are summarized and
discussed. The difference of thermal expansion coefficient and pressure between the core and the panels may be the chief
reasons. This paper will analyze the mechanics behavior of metal honeycomb sandwich structure in the course of the
vacuum high temperature braze welding, then make sure the reasons and get a way to solve it. Haynes214 is a good
material of face sheet at present. γ - TiAl and microlaminate materials are the candidate materials in the future.
