Title: Slotted one-half power law nose cone for aerospace applications
Inventor: SONAWWANAY PUSKARAJ D
Filed: 2023-02-28
Abstract: The present invention relates to slotted one-half power law nose cone for aerospace applications. The invention focuses on providing a substitute or a variation for the current nose cone in use throughout aerospace and aeronautical applications. By implementing slots based on helical or elliptical or parabolic or one half power law curves along the outer surface of the nose cone, originating from the uppermost tip and extending to the elliptical base of the nose cone. Field- Related to nose cones of missiles, aircraft, and other aerodynamic bodies, with slots engraved on the conical surface along some curve equation to increase aerodynamic efficiency.
