Application Of Active Noise Control To Reduce Cabin Noise In Single Engine General Aviation Aircraft, Jeroen Hendrik Dolmans
Application Of Active Noise Control To Reduce Cabin Noise In Single Engine General Aviation Aircraft, Jeroen Hendrik Dolmans
Master's Theses - Daytona Beach
The application of active noise control to reduce cabin noise in single engine, general aviation aircraft is investigated through the use of the 'filtered x' least mean square algorithm and a simple acoustic feedforward method to generate a reference signal is tested. The system is designed to utilize one reference signal and up to two feedback signals and two audio speakers. The feedforward system consists of a microphone placed in close proximity to the front windshield and isolated from the cabin noise. Cabin noise and reference signals are recorded during flight in a Cessna 172 Skyhawk, a Piper Cherokee 140 …
Interactive Approach For Geometry Definition With Automatically Differentiated Sensitivities For Practical Airplane Design, Yvette Cordero
Interactive Approach For Geometry Definition With Automatically Differentiated Sensitivities For Practical Airplane Design, Yvette Cordero
Mechanical & Aerospace Engineering Theses & Dissertations
First, a newly developed interactive surface generation tool is described for the conceptual design phase and aerodynamic shape optimization of aircraft. The new design tool is called Interactive Rapid Airplane Parametric Input Design (IRAPID) for fuselage and wing body configurations, and Blended Wing Body (BWB) generator for flying wing configurations. The development of the software is based on the RAPID methodology, which incorporates a partial differential equation approach to surface design. By incorporating physical airplane design parameters into the boundaty conditions of the partial differential equation, the solution surface of a wing configuration is generated. The construction of fuselage components …

The Pratt & Whitney 4060: Power For The Future, Gregory Sumner
The Pratt & Whitney 4060: Power For The Future, Gregory Sumner
Honors Theses
The Pratt & Whitney 4000 engine platform is considered the most economical turbofan engine in its class. It is advertised as providing the most efficient service and the most reliability for air carriers. United Airlines utilizes the company's engines. The paper begins with basic turbine engine theory and moves on to engine classifications, where the Pratt & Whitney 4060 is introduced. The systems are covered in detail. Maintenance areas of service and inspections are described to show how personnel may interact with the computers. Finally, a description of activities during the author's internship describe the interesting facets of a semester …
