General Aviation Aircraft: A Comparative Analysis Of Analog Instrument Display And Conceptual Primary Flight Display, Ungul Laptaned
General Aviation Aircraft: A Comparative Analysis Of Analog Instrument Display And Conceptual Primary Flight Display, Ungul Laptaned
Master's Theses - Daytona Beach
The primary purpose of this study was to evaluate the effects that analog instrument display versus primary flight display (PFD) had on pilot performance. Pilot performance was evaluated by: (a) time, and (b) number of errors. There were twenty subjects with a minimum of a private pilot license selected from the Aeronautical Science department at Embry-Riddle Aeronautical University. Three flight conditions (spoiler problem, engine problem, and flap failure) acting as a control group was given to the flight students while flying a traffic pattern. A Silicon Graphics® flight simulation software program and a video camera were used as the data …

An Intermittent-Combustion General Aviation Aircraft Engine Exhaust Noise Prediction Algorithm, Hiroko Tada
Master's Theses - Daytona Beach
From an environmental point of view, the reduction of aircraft noise has become an important factor recently. There are two factors that make airplane noise: propeller noise and engine noise. This report puts emphasis on only the engine noise in order to begin understanding what airplane engine exhaust noise is. At first, the engine exhaust noise is comprehended using the Dobrzynski's engine noise theory. Next, a discussion about an Embry-Riddle Aeronautical University (ERAU) engine system, engine exhaust system configurations, and microphone setting standards that show the ERAU engine system exhaust noise data. Finally, an Intermittent-Combustion (IC) General Aviation (GA) aircraft …
Designed Reduction Of Radiated Noise Characteristics From Two-Bladed General Aviation Propellers, Chandra K. Stich
Designed Reduction Of Radiated Noise Characteristics From Two-Bladed General Aviation Propellers, Chandra K. Stich
Master's Theses - Daytona Beach
In recent years increased public awareness has made the reduction of environmental noise pollution a top priority for the aviation industry. Utilizing current technology, this study examines the reduction of noise generated by two bladed general aviation propellers, through design. The Aircraft Noise Prediction Program - Propeller Analysis System (ANOPP-PAS) is used to predict the noise and performance characteristics for an industry typical reference propeller as well as for the final quiet and efficient design.
This investigation is based on the use of a 200 hp engine rotating a 76 inch propeller. Typically, such a propeller would be rotated at …
