The group was tasked with designing a 3D printed glider. The scope of this assignment is to someday use the developed glider design and equip it with electronics and controls to deliver medical materials to remote areas in drone-like fashion. The glider was to be designed so that it could be printed using a lower-end, compact, and relatively portable 3D printer for optimal field efficiency. For this reason, the makerbot 3D printer was selected. The compact base plate of the makerbot printer left the team with strict size limitations, so the glider was printed in a series of nine parts …

Design Of Shape-Conforming Nosecone For Optimal Fluid Flow From Transonic To Supersonic Range, Anna Tombazzi

Modern flight vehicles, such as rockets, missiles, and airplanes, experience a force caused by forebody wave drag during the flight. This drag force is induced when the frontal point of each vehicle breaks the pressure wave during flight. Efforts to reduce this wave drag force to improve flight efficiency include modifying the nosecone profile of the flight vehicles to lower the drag force.

This project revolved around creating a design to make the transformation of nosecone shapes from a ¾ Parabolic profile to a ½ Power Series profile possible, mid-flight. Using a novel nosecone assembly, shape memory alloys (SMAs) and …
