Aryan Kapoor of JRD Propulsion spent three years successfully planning and executive a SpaceX-like model rocket vertical landing. What he ended up with was a rocket equipped with two solid-propellant motors stacked atop of each other, one for ascent and the other handling descent as well as landing duties.
The two motors are housed in a 3D printed gimbal mount with two servos that give the stack + / – seven degrees of thrust vectoring in two dimensions. Vectoring is controlled by a custom flight computer that is connected to a barometric altimeter and an inertial measurement unit. Rubber bands are used to absorb landing forces, while syringes act as dampers.
