发明名称 Elliptical ram air pressurized airfoil parachute
摘要 An improved parachute utilizing a ram air design and having an upper surface connected to a lower surface by a plurality of rib members and forming a plurality of chambers therebetween. The end chambers are smaller than the center chambers and this increases the lift-to-drag ratio of the parachute. The parachute has a substantially elliptical planform so as to increase the aspect and glide ratios of the parachute.
