System, apparatus, and methods for a nosecone and propulsive nozzle
View Patent ↗A nosecone apparatus for hypersonic aircraft, rocket or missiles using a method for the mitigation of the created the shock front of a rocket or aerospace plane flying at hypersonic speeds by using nosecone splines to create both centripetal and isentropic airflows in conjunction with regeneratively cooling the nosecone structure.
1. An apparatus for mitigating a shock front of a nosecone that operates at hypersonic speed comprising:
a nosecone, said nosecone having a nosecone intake proximately disposed to accept a flow of air; the nosecone intake having a funnel shaped surface, the large end of the funnel shape surface proximately dispose to the intake;
a shaft, the air inlet end of the shaft connected to the nosecone intake for directing the flow of air over the funnel shaped surface, and an outlet end of the shaft that transporting the flow of air;
an outlet funnel, said outlet having a second funnel shaped surface, the small end of the second funnel shaped surface connected to the outlet end of the shaft;
an expansion nozzle, said expansion nozzle having a inlet end and an outlet end, the inlet end connected to the large end of the second funnel shaped surface;
a means for cryogenically cooling the second funnel shaped surface;
such that the overall drag on the nosecone is reduced.
