Derivation And Exploration Of Analytical Aircraft Stability Analysis, Roderick Landreth

Honors Theses

A comprehensive measure of the in-flight stability of an aircraft is essential, though it can take a large amount of resources to do accurately and usefully. Small companies and colleges often don't have the resources to attain accurate experimental or analytical data to describe stable flight before potential failure. This composition investigates methods of completing a static and dynamic stability analysis for an aircraft feasible for a college, small business or hobbyist to complete, with the goal to eliminate the 'barrier of entry' concerning a lack of information and resources. A sample analytical calculation for static stability of Union College's …

Role Of Diagnostic Monitoring Software Versus Fault-Tolerant Components In The Development Of Spacecraft Avionics Systems, Andrew Attorri

Honors Theses

In any spacecraft, there are several systems that must work simultaneously to ensure a safe mission. One critical system is the ‘avionics’ system, which is comprised of all of the electronic controls on-board the spacecraft, as well as radio links to other craft and ground stations. These systems are present for both manned or unmanned spacecraft.

Throughout the history of spaceflight, there have been several disasters related to avionics failures. To make these systems safer and more reliable, two main strategies have been adopted. The first, more established approach is through use of fault-tolerant components, which can operate under a …

Land, Air, Sea, Rover (Lasr) - Unmanned Vehicle, Gabriel Prescinotti Vivan

Honors Theses

This senior design project encompassed the optimization of a previously built quadcopter, as well as the design of new components for additional functions and increased range of operations. The previous vehicle was designed to operate as a helicopter, land rover, and submarine. Although the vehicle operates successfully in these three environments, it is not very successful on transitioning between them, i.e. cannot take off from underneath water. This year’s project goals included optimizing the current vehicle so that it could transition seamlessly between its functions and adding an additional function: to be able to rover at the bottom of a …

Cubesat Adcs Validation And Testing Apparatus, Jacob Stevens

Honors Theses

The WALI team at Western Michigan University requested a test environment to validate their CubeSat’s de-tumbling control system and hardware. The test environment required a Helmholtz cage and spherical air bearing. The Helmholtz cage provides an adjustable magnetic field to simulate low earth orbit; the spherical air bearing simulates the friction free environment the CubeSat will experience in space. In conjunction, the two components create an adjustable system that simulates a satellite in low earth orbit.

Development Of Long Endurance Small Unmanned Aerial System, Andreas Quainoo

Honors Theses

The purpose of this Senior Design Project is to design, build, and test an Unmanned Aerial System (UAS). This will be used as a test platform for airborne electronics. The intended capabilities of this project include a 12-hour flight time, the ability to carry 5 lbs of payload, and the ability to recharge the batteries of electronics while in the air. With these parameters in mind, the focus of the design was on endurance, and, by extension, efficiency and durability. Upon completion, the aircraft and its onboard systems was constructed and evaluated. Secondary products of this project include an instrumented …
