Vehicle Sizing PDR

This presentation delves into the preliminary sizing of an aircraft, focusing on critical aspects such as weight estimates, wing loading, and power loading. We utilize a methodical approach to estimate fuel fraction, analyze energy requirements for various mission phases, and determine battery weights. Key findings reveal a total aircraft weight of 5.42 lbs, with a wing area of 4.3 ft² and a motor horsepower of 1.8 hp. The analysis also outlines stall, cruise, and climb constraints, providing a comprehensive overview of design considerations for optimal performance.
