The impact of film cooling on the heat release within a rotating detonation combustor
Autor: Shreyas Ramanagar Sridhara, Antonio Andreini, Marc D. Polanka, Myles D. Bohon
Publikováno v: Applications in Energy and Combustion Science, Vol 20, Iss , Pp 100300- (2024)
Rotating detonation combustors establish a detonation wave that continuously circulates inside a small annulus. The presence of the detonation wave and the downstream oblique shock within the small annulus coupled with high mass flow induces a high h

Investigation of In-Cylinder Pressure Measurement Methods within a Two-Stroke Spark Ignition Engine
Autor: Joseph K. Ausserer, Marc D. Polanka, Paul J. Litke, Keith D. Grinstead
Publikováno v: SAE International Journal of Aerospace. 17
This work describes an investigation of measurement techniques for the indicated mean effective pressure (IMEP) on a 55 cc single-cylinder, 4.4 kW, two-stroke, spark ignition (SI) engine intended for use on Group 1 and Group 2 remotely piloted aircra

Correlations for the Performance, Efficiency, and Energy Losses for Single Cylinder, Four-Cycle Internal Combustion Engines With Displaced Volumes Ranging From 40 to 200 cc
Autor: Jason R. Blantin, Marc D. Polanka, Joseph K. Ausserer, Jacob A. Baranski
Publikováno v: Journal of Engineering for Gas Turbines and Power. 145
Five commercial-off-the-shelf (COTS) engines ranging from 40 to 200 cc were tested as potential power plants for Group Two RPAs. The maximum brake power ranged from 1.8 to 5.0 kW. Of the five engines, two were designed for hobby aircraft (similar in

A Resistive Model to Characterize Overall Effectiveness Influenced by Multiple Coolant Temperatures
Autor: James L. Rutledge, Matthew N. Fuqua, Marc D. Polanka, William P. Baker
Publikováno v: Volume 6A: Heat Transfer — Combustors; Film Cooling.
The surface temperature of a film cooled turbine hot gas path component is typically nondimensionalized according to the overall effectiveness. This nondimensionalization scheme takes advantage of the fact that the surface temperature must be bounded

Radial Rotating Detonation Engine Driven Bleed Air Turbine
Autor: Scott A. Boller, John Hoke, Riley Huff, Marc D. Polanka, Frederick R. Schauer, Matthew L. Fotia
Publikováno v: Journal of Propulsion and Power. 37:252-260
There has been a recent need for rapid response power generation device on aircraft. Current power generators consume a large portion of the aircraft’s usable volume, and they are also extremely he...
