Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

Use of Reflex Airfoils Ever notice how many tailless aircraft have wings that curve at the trailing edge? This type of design is a reflex airfoil. The reflexed shape of the airfoil usually causes a positive (nose-up) pitching moment coefficient at its aerodynamic center. Flying wings dont have tails or elevators.

These glove modifications served to smooth the wing surface and alter the airfoil to achieve specific pressure distributions. View of the cockpit of NASA’s F-14, tail number 991. For the VSTFE program, the outer wing panels of NASA 834 were fitted with specially designed natural laminar flow gloves.

Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

Making the wing relatively flat on top with a blunter leading edge and more curvature on the bottom gives you a supercritical airfoil. Monitoring Mach Number in the Cockpit Since IAS fails to accurately estimate speed at high altitudes, pilots switch to the Mach scale to manage their speed once they’re in a high-altitude cruise.

FAA Releases Powered-Lift Certification Guidance

Flying Magazine

For lift during horizontal flight, they use rigid airfoils such as wings. Certifying Powered-Lift The AC defines powered-lift as heavier-than-air aircraft that use “engine-driven lift devices” or engine thrust for vertical takeoff and landing and low-speed flight.
