The Bold, Bulbous Douglas 1015 Cloudster II

Flying Magazine

An unbuilt concept, the Douglas DC-8 Skybus aimed to position two V-12 piston engines in the forward fuselage and link them with two contra-rotating propellers in the tail. A ventral stabilizer doubled as propeller protection in the event of over-rotation or tail strikes. Neither aircraft would advance beyond the development stage.

Raptor-Inspired Drone Could Lead To Increased Maneuverability

AV Web

A pair of aerodynamic researchers at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have created a raptor-inspired drone that uses its tail feathers to control bank, rather than wingtip feathers mimicked by ailerons on airplanes. The turns could be executed at low and high speeds as the raptors maneuvered.

Today in Aviation History: First Flight of the Consolidated B-24 Liberator

Vintage Aviation News

Davis, who had developed a new wing, whose airfoil had a lower drag co-efficiency than other wing designs of the time, and which had already been used on the company’s Model 31/XP4Y Corregidor flying boat. Originally flown under the historic schemes for All American and The Dragon and His Tail , it is now painted as Witchcraft.

Why Aircraft Need Vertical Stabilizers, But Birds Don't

Simple Flying

Aircraft are fitted with wingtip devices, generally known as winglets or sharklets, to minimize aerodynamic drag and increase fuel efficiency, and state-of-the-art engines reduce sound and wear and tear. Significant advances in aviation technology have occurred over the last few decades.

The Unfulfilled Promise of the Fairchild T-46

Flying Magazine

The most significant visual differences were the T-46’s high wing and the “H” tail, with twin vertical stabilizers mounted to the ends of the horizontal stabilizer that strongly resembled those of the company’s previous jet, the A-10 Thunderbolt II. As outlined in a U.S.

Today in History:  First flight of the Sikorsky S-72

Additionally, the S-72 was equipped with a low-drag fuselage, allowing it to achieve a maximum speed of 340 knots in a dive. Notably, one significant test involved measuring the vertical drag of the airframe using the main and tail rotor load measurement system, further contributing to valuable data in rotorcraft aerodynamics.

High Wing or Low Wing – Which Trainer Should I Choose?

Flight Training Central

Those struts and wires create a lot of parasite drag, an anathema for aircraft whose design and mission is speed. Then in 1956 Cessna moved the tail-wheel on the 170 to the nose and the resulting high wing 172, with well over 40,000 copies, became the best-selling civilian aircraft in history. The bi-wing design has one serious flaw.
