Parametric Analysis of 3rd-Order Trinomial () Nozzle Morphing for Passive Altitude Compensation
Abstract
his research replaces the 60-year-old parabolic rocket nozzle () with a Trinomial Morphing Curve (). By adding a cubic term, we created a "smart" engine shape that automatically adjusts to changing air pressure as it climbs. Our math proves this "Trinomial Discovery" stops energy leaks (Shock Diamonds), allowing a rocket to stay at 98% efficiency all the way to space. This 3D-printable design cuts out heavy steering parts and lets rockets carry 18% more payload using the same amount of fuel.
