Design and evaluation of a thermal nozzle for small-scale turbojets
(2022-05)
This paper presents the design and evaluation of a thermal nozzle for small-scale turbojets. Historically, small-scale turbojets have suffered from poor thermal efficiency and thrust specific fuel consumption (TSFC). This ...
Computational analysis of sweeping jet actuator using dynamic mode decomposition
(2022-12)
A sweeping jet actuator (SJA) is a self-sustaining, periodically oscillating device without involving any moving parts. SJA requires only pressurized fluid at the inlet to transfer momentum via the Coanda effect. As an ...
Quantitative analysis of positive-displacement compressor models tested in extrapolation scenarios
(2022-12)
Testing and evaluation of select semi-empirical compressor models is carried out to quantify performance in modulation (variable speed), extrapolation, and additionally, variable superheat scenarios. Three representative ...
Information aware flight path design for flow field estimation and performance investigation of active flow control aircraft controllers
(2022-12)
This thesis discusses the feasibility and performance of implementing a COTS reciprocating piston compressor for a developed active flow control (AFC) actuation framework to quantify the aerospace-relevant performance ...
Investigation of a tilt-wing proof of concept for a high-speed VTOL jet UAV using thrust vectoring for balance
(2022-12)
Success of Special operations forces (SOF) missions depends on a high level of situational awareness within sensitive areas of interest, especially when arriving in volatile, sensitive environments. Oftentimes intelligence, ...
