Thermal Analysis Of The Temperature Gradient Across Pintle Injector Face, Zoe Brand Jul 2022

Thermal Analysis Of The Temperature Gradient Across Pintle Injector Face, Zoe Brand

Discovery Day - Prescott

Proper analysis of the temperature gradient across the pintle injector face is a complicated surface to acquire a reading from. Complications arise from the extreme temperatures seen on the combustion side mixed with the ambient temperatures seen on the fuel side of the injector. The orientation of temperature sensor placement is critical to mitigate hot spots and not disrupt the thermal flow through the injector face. The installment of the temperature sensors is also a critical issue since a new medium would need to be added to keep the sensor in place. The goal of this research is to figure …


Effects Of Equivalence Ratio During Shutdown Of A Rocket Engine On Hardware Longevity, Benjamin Black Jul 2022

Effects Of Equivalence Ratio During Shutdown Of A Rocket Engine On Hardware Longevity, Benjamin Black

Discovery Day - Prescott

During the shutdown or purge period after firing of a rocket engine it is critical to understand what equivalence ratios are desirable and implement a shutdown sequence so that the hardware is subjected to the lowest thermal and mechanical loading. Furthermore, it is essential that hazards to the test technicians caused by this method be minimized. The initial study was conducted into combustion mechanics, to understand how the reactants would ideally behave at varying equivalence ratios and in both pre-mixed and diffusion flame combustion. Using this foundation an analytical model for a Propane-Oxygen flame was created and tested using a …


Tip Driven Rotor System, Kevin Allyas Jul 2022

Tip Driven Rotor System, Kevin Allyas

Discovery Day - Prescott

The Tip-Driven Rotor System (TDRS) Project is a product designed for KRyanCreative, LLC (KRC), as the basis of a Levitated Annular Rotor System (LARS) for commercial and tactical military vertical takeoff and landing (VTOL) vehicles. Conceptually, this design will greatly increase power density and lift capacity over conventional shaft-centric helicopters. The design also enables variable rotational velocity control that can greatly expand the VTOL flight envelope. The LARS innovatively leverages electromagnetism and superconductive levitation in the transfer of energy from vehicle source to aerodynamic lifting surface. The benefits of LARS include: the reduction of wing tip vortices due to a …
