Design and Analysis of a Multi-Engine General Aviation Trainer Aircraft

Senior Design Project, Supervised by Dr. Sudip Bhattrai

• Designed a preliminary model of a multi-engine general aviation trainer aircraft capable of STOL operations.
• Conducted tests on the model to assess static and dynamic stability, handling qualities, and various maneuvers using a flight simulator.
• Studied the aerodynamic properties on a scaled-down 3D printed model in a low-subsonic wind tunnel.
• Presented the design and corresponding results in the Annual Aircraft Design Review hosted by the Department of Mechanical and Aerospace Engineering, Pulchowk Campus.

Design and Fabrication of a Medical Delivery Drone

for the AIAA Design, Build, and Fly (DBF) Competition-2022

• Studied the effectiveness of UAVs’ usage in delivering medical and critical emergency supplies in rural areas.
• Led design and analysis team contributing directly to the conceptual and detailed design of the fixed-wing medical drone.
• Developed a conveyer-based payload drop-off mechanism capable of holding and unloading 4 medical payload pallets, weighing 8 ounces each, in a mission-specified pattern.
• Conducted structural analysis of the UAV components and performed experimental works for the ground and flight testing of the UAV.

Design and Fabrication of a 4-axis Hotwire CNC Foam Cutter

for the AIAA-DBF Club

• Designed and fabricated a 4-axis Hotwire CNC Foam Cutter to shape styrofoam panels to the desired form for wings and empennage.
