Resumen del Editor

The paper by Mathew J. Lewallen, submitted for the course SPST 615: Aerodynamics at American Military University, analyzes the aerodynamics of the Gulfstream G550 twin-jet aircraft. The study's objectives include determining the drag coefficient, lift coefficient, and the lift to drag ratio over varying flight velocities from 50 to 1150 feet per second. Using the given drag coefficient formula and standard atmospheric density at 41,000 feet, the paper calculates these coefficients. The maximum velocity is estimated based on where the lift and drag coefficients level off in the graphs, around 400 to 450 feet per second. Ideal cruise speed is discussed in relation to the Gulfstream G550's specifications, affected by factors such as air traffic control and wind speeds, and is roughly 950 feet per second. Maximum endurance is tied to the aircraft's optimal fuel consumption, factoring in climbing, cruising, and descending phases, with a max range of 6750 nautical miles. The paper highlights the importance of these aerodynamic parameters in aircraft design, where they guide the balancing act between different performance aspects to meet specific mission requirements.
