Film Cooling In Gas Turbine And Nozzle, Manideep Uduta Engineer-Graduate Aerospace, Vaibhav Naiknavre Engineer-Graduate Aerospace

Graduate Research in Engineering and Technology (GRET)

A gas turbine is a rotating engine that generates its power through the flow of combustion gases. With either an axial or centrifugal compressor, air from the surrounding environment is drawn into the engine intake, where it is compressed and heated before being sent to combustion chamber. Every gas turbine engine has a nozzle as a standard part. Among its many responsibilities include propelling the engine forward, returning exhaust gases to the free stream, and regulating mass flow through the engine. When the power turbine's exhaust exits, the nozzle is directly in the direction of the fumes. Simply put ...

Aerodynamics Of Forward Swept Wing., Muqeeth Sharif, Mohammed Abbas, Mukarram Hussain

Graduate Research in Engineering and Technology (GRET)

A forward-swept wing is an aircraft wing configuration in which the quarter-chord line of the wing has a forward sweep. Typically, the leading edge also sweeps forward. Forward swept wing is proposed with the goal of enhancing performance and controllability during high angle of attack perching maneuvers. Data is presented from a series of XFLR5 analysis to qualify the aerodynamic effect of forward swept over a range of angle of attack from -25º to +75º. Various graphs were obtained during this analysis which indicates that the forward swept wing configuration can achieve qualitatively different low cost perching maneuvers.


Characterizing And Predicting Human Visual Perception Of Unmanned Aerial Vehicle Gestures, Paul Fletcher 2022 University of Nebraska-Lincoln

Characterizing And Predicting Human Visual Perception Of Unmanned Aerial Vehicle Gestures, Paul Fletcher

Computer Science and Engineering: Theses, Dissertations, and Student Research

Unmanned Aerial Vehicles (UAVs) are being used in public domains and hazardous environments where effective communication strategies are critical. UAV gesture techniques have been shown to communicate meaning to human observers and may be ideal in contexts that require lightweight systems such as unmanned aerial flight, however, this work may be limited to an idealized range of viewer perspectives. As gesture is a visual communication technique it is necessary to consider how the perception of a robot gesture may suffer from obfuscation or self-occlusion from some viewpoints. This thesis presents the results of three online user-studies that examine participants’ ability ...

Novel Thermal Coating For High-Speed Airplanes, Abinash Satapathy, Lakshay Battu, Liam Watson, Nazanin Rajabi

Symposium of Student Scholars

In comparison to various other materials, Carbon Fiber, specifically Carbon Fiber Reinforced Polymers (CFRP), is pre-eminent amongst other materials for use on aeronautical systems. Due to its high specific strength (strength-to-weight ratio), CFRP is prominent for carrying heavy loads while maintaining a lightweight build. However, when influenced by heat resulting from air resistance, CFRP is known to undergo serious degradation that would significantly decrease the effectiveness of the polymers. To prevent this degradation and maintain the strength of the CFRP, thermal protective layers (TPLs) are designed to shield the CFRP from heat exposure. This research is focused on the examination ...

The delta wing is best known for their contribution to stability and also, they have high structural advantages compared to other wings. Till now the delta wing has been used mostly in high speed or high Reynolds number flows. But no one concentrated on the low Reynolds number flows, here we have analyzed the flow at Re = 100000. Since we have taken the case of this Reynolds number range, the results obtained can be utilized in designing the Micro Air Vehicles (MAVs) which are mostly designed for the range of Reynolds number Re = 10000 to 100000.
