Blended Wing Body Propulsion System Design, Parth Kumar, Adeel Khalid
International Journal of Aviation, Aeronautics, and Aerospace
This research paper focuses on the optimization of the propulsion system of a blended wing body design. Two different aspects of the design, the engine placement and count, and the engine itself, are investigated. The preliminary wing of the BWB is created through aerodynamic analysis, and is kept as a constant over the different propulsion system configurations. The engine parameters are first investigated. Equations are derived to express takeoff distance and climb rate as a function of engine sea level thrust, cruise thrust, and the number of engines. Nearly 150 different engine models, in BWB configurations of 2, 3, 4, …

Cruise Missile Integrated Air Defense System Penetration: Modeling The S-400 System, Michael Pelosi, Amie K. Honeycutt
International Journal of Aviation, Aeronautics, and Aerospace
This research determines improved flight-path routes that make maximum utilization of terrain-masking opportunities, and defending radar and missile system equipment performance and launch timing constraints, in order to avoid radar detection and tracking, and to mitigate subsequent missile shoot-down risks. The problem is formulated as one of constrained optimization in three dimensions. Advantageous solutions are identified using the A* Algorithm in conjunction with detailed equipment performance and constraint calculations and high-resolution digital terrain elevation maps. Topographical features in digital terrain are exploited by the algorithm to avoid radar detection and tracking. The model includes provisions for all-aspect/all-frequency radar cross section …
Professional Pilot Commercial Off-The-Shelf (Cots) Efb Usage, Policies And Reliability, Tyler A. Babb
Professional Pilot Commercial Off-The-Shelf (Cots) Efb Usage, Policies And Reliability, Tyler A. Babb
International Journal of Aviation, Aeronautics, and Aerospace
Electronic Flight Bags (EFBs) have flooded the aviation industry. Commercial off-the-shelf (COTS) tablets are now commonly used by pilots as EFBs. Operators use EFBs for ease of use, faster access to information, to remove weight from the aircraft, and to increase pilots’ quality of life. Identifying trends in EFB usage among professional pilots could benefit operators and universities with flight training programs. EFB policies and procedures may vary among operators but achieve FAA compliance. This study identified these policies and procedures. The types of devices and software vary, and identifying these devices and software could be useful. This research used …
