Aerospace Engineering: Aircraft Fundamentals

Explore general aviation within aerospace engineering, including the distinction between utility aircraft and private jets, with examples like the Cessna 172 and Gulfstream G550, and notes on air-cooled piston engines.

Explore commercial aircraft, or airliners, designed to transport passengers and cargo while airlines optimize routes for efficiency, fuel consumption, payload, and reliability, with a nod to history and sustainability.

Explore military aircraft—fighters, bombers, attack aircraft, transport, and spy planes—and trace their evolution from early Wright models to modern stealth designs.

Explore how lift, weight, thrust, and drag interact to govern aircraft motion, with lift and drag tied to velocity and wing area while weight remains constant.

Learn how airfoil geometry and motion generate lift and drag, via Newton's third law and Bernoulli effects, and study chord line, camber, thickness, and angle of attack.

Analyze how 3D wing geometry affects lift and drag, showing nonuniform lift distribution along the wing, downwash and induced drag from wingtip vortices, with wing tips reducing drag.

Explore wing configurations and trade-offs between aerodynamic performance and manufacturability, including elliptical, tapered, constant-chord, and delta wings, plus aspect ratio and practical considerations.

Explains how high lift devices, including flaps and slats, increase the coefficient of lift and delay stall, enabling takeoffs and landings at lower speeds.

Explore the transition from laminar to turbulent flow over wings, its impact on lift and stall, and how wing design, slats and pilot maneuvers mitigate loss of control.

Learn how jet engines produce thrust by compressing air, mixing with fuel in the combustion chamber, and expanding through the turbine and nozzle, with turbojets, turbofans, and turboprops.

Explore inlet design for aircraft engines, detailing how front-positioned, smooth lips guide air into subsonic and supersonic engines, maintain flow with minimal disturbance, and mitigate shock waves.

Learn how compressors raise air pressure by converting rotor energy into flow pressure across multiple stages, using axial and centrifugal designs with rotating airfoils and high mass flow.

Describe how air and kerosene fuel mix inside combustion chambers with injectors and swirl vanes to generate thrust in turbofan engines, including Jet A and Jet B fuels and auto-ignition.

Explain how turbines decrease pressure to accelerate flow and generate shaft power for the compressor, and how nozzles and afterburners boost thrust.

Compare turbojet and turbofan propulsion, detailing hot and cold flow, compressors, turbines, nozzles, afterburners, and thrust optimization for subsonic and supersonic flight.

Explain the center of gravity as the aircraft's average mass point and its effect on stability, with center of pressure near one fourth of the wing chord relative to gravity.

Explore how control surfaces—ailerons, elevators, and rudders—manipulate lift to roll, pitch, and yaw for aircraft maneuvers, including crosswind landings.

Define the key aircraft weights—MTW, ZFW, maximum zero fuel weight, OEW, and takeoff weight—to explain how payload, usable fuel, taxi out fuel, and reserves influence takeoff and landing limits.

Understand how range defines the maximum distance from takeoff to landing, and how the payload range diagram shows fuel versus payload trade-offs under a constant maximum takeoff weight.

discover how Breguet equations relate aircraft range to velocity and time of flight, and how maximizing lift-to-drag, specific impulse, and the Napoleon logarithm of the initial-to-final weight ratio extends range.

Explore core aircraft components, from fuselage and wings to engines, winglets, flaps, slats, spoilers, and empennage, and see how airfoil geometry, angle of attack, and camber affect lift and drag.
