AJAS · 2022
Engineering
The most theoretically efficient airplane design is the flying wing due to its simplicity, resulting in low weight and low drag compared to more conventional configurations. However, a perfe…

Engineering
The goal of this project was to develop a low-cost spectrometer suitable for demonstration experiments and educational programs. The price point of about $50, easy to source components, and…
AJAS · 2022
Engineering
This project examines if an object supported by a wing structure filled with hexagons will be more mass efficient than solid filled support structure. Aircraft are a large source of greenhou…
AJAS · 2020
Engineering (inferred)
Vortex Induced Vibrations (VIV) are a phenomenon where the fluid flow causes oscillations against an object called a bluff body by vortex shedding. This phenomenon has recently been studied…
AJAS · 2019
Engineering (inferred)
Physical winglets offer widespread lift to drag force improvement for commercial and cargo aircraft; unfortunately, their improvements cannot be applied to fighter or short take-off and land…
AJAS · 2018
Engineering (inferred)
All Choked Up: The Effect of the Convergent Section Half-Angle on the Thrust of a Cold Gas Rocket continues my investigation of cold gas rocket nozzles. Rockets and Nozzles and Thrusts, OH M…
AJAS · 2018
Engineering (inferred)
The empennage, or tail, of an aircraft plays a vital role in aircraft structure and function. Four forces act upon each part of an aircraft: lift, drag, weight, and thrust, with lift and dra…
AJAS · 2018
Engineering (inferred)
The purpose of this project was to see if using a frontward pulling propellor gives the multirotor a higher velocity than the multirotor altering its pitch or yaw to achieve movement in a gi…
AJAS · 2017
Engineering (inferred)
The problem of excessive exposure to aircraft noise has persisted since the dawn of aviation. The Federal Aviation Administration’s regulations thus require airplanes to make detours in orde…
