Other than this small orientation problem - This is a fantastic piece of work! Well done!!!
I wonder how robust the wingfold mechanism was supposed to be? In he event of an off nominal separation or a launch abort, the wings would have to extend quickly and would be exposed to large aero forces. Perhaps it had ejection seats?
Very interesting vehicle; don't think I've ever heard of it before!Wouldn't the mechanism for folding the wings add too much extra weight and detract from the amount of payload that could be carried, or was LKS only intended to carry fairly light payloads?Also, wouldn't the joints in the wings pose extra difficulties with regards to the TPS?
Giuseppe, this really is excellent work! It is with great respect that I admire your abilities.There remains volumes of notes concerning the LKS, but until then this will be the standard reference. I think Chelomei would be proud!Respectfully,David L. Rickman549 Caribou RoadAsheville, NC 28803USA
Here it is.CiaoGiuseppe
The folding wing was successfully proved with the small scale Bor-4 demonstrator. It was launched several times during early-mid 80's.The Bor-4 utilized the wing folded during the re-entry phase in ordert to minimize the drag in this phase, once that the Spiral/bor-4 reached the dense air the wings were lowered down in order to achieve a runaway landing (or a slow speed splashdown in the case of Bor-4).Regarding LKS the wings were folded during launch in order to reduce the drag in this phase and not during re-entry were the wings were fully deployed. So in this sense the LKS was less demanding for its TPS rather than the Spiral/Bor-4 concept.Interstingly, the Spiral/Bor-4 was the baseline for the HL-20/Dream Chaser development with the only difference that American never considered seriuosly to apply the folding wings concept.
Not more dangerous than fly on Titan II or III rocket. Chelomei intended by since the Proton rocket to be man rated for a various range of manned spacecraft, as follows:
