Winglets and Sharklets Both Airbus and Boeing operate aircraft with wingtip devices that are designed to increase aircraft efficiency by removing drag. The devices would prove to “reduce wingtip drag” and increase “fuel efficiency by 6-7%” but would need be positioned uniquely for each aircraft type.
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.
Additionally, the interior and paint were done in 2001/2002 and still show like new, To make an already quick and efficient airplane even more slippery, a previous owner has installed a number of drag-reduction modifications. These include a new nose bowl and dorsal fin/tail root fairings from Lasar Speed Mods.
Its connected, along with a safety weak link, to the tail of the airplane. With skill (and some luck) the hook catches, the plane roars up to not drag the fabric along the ground, and the whole assembly is hoisted into the air. Dropping the banner removed its drag, but only pitching down would have escaped the stall.
As seen from the aircrafts tail, the vortex rotates in the anti-clockwise direction on the right wingtip and the clockwise direction on the left wingtip. This horizontal component of lift is called Induced Drag. Its called induced drag since it only exists as a consequence of lift. Increased Drag Moving air around is hard work!
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.
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.
The system is well-suited for aircraft of any size, and offers low power consumption and reduced drag from its low-profile antenna. It is designed as a tail mount antenna, and operates on Viasat GX and next-generation networks, which makes it especially suitable for mid-sized business aircraft.
However, since Convair was also developing the XF-92 delta wing prototype for a future Air Force interceptor, the design team at Convair, led by Ernest Stout, proposed a new delta wing aircraft with retractable hydro-skis for takeoffs and landings, a watertight hull, and a single delta tail.
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 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.
Understanding the Basics of Flight Principles of Flight: Lift, Weight, Thrust, and Drag Flying a plane for the first time requires a basic understanding of the forces that make flight possible. Thrust, produced by the engines, moves the plane forward, while drag, or air resistance, slows it down.
I don’t which part irks me more: the boring typeface, the blank bottom, or the tail emblem, which is a neutered version of the one it replaces. Then we have the tail. GRADE: D-minus MINTY FRESH JetBlues livery features a grab bag of different tail patterns. Where do we start? Do we have any idea what this means?
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.
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.
The airship initially recovered, dumping ballast and stabilizing at 700 feet above the sea and returning to its cruising altitude of 1,600 feet, but the ship was sent into another plunge, falling a rate of 14 feet per second tail-down.
Around this time, the USAAF was also developing its first jet fighters, but knew that all-jet aircraft at this time were short-ranged and burned fuel quicker than propeller-driven aircraft, and so the optimal design was to feature a propeller-driven engine in the front for long range performance and a jet engine in the tail for high speed in combat.
The tradition of cutting the shirt tail of a student pilot after their first solo flight dates back to the early days of aviation. There are a few references to where this came from historically – let’s explore the heavy plane tail, the clipping, of birds wings, and the Navy.
Below are other critical pieces of the wings that help give the plane additional lift, reduce drag, or achieve lower speeds in preparation for landing: Ailerons: A French word meaning “fin” or “little wing,” the aileron helps control the airplane’s roll. What are the basic parts of this section?
This is consistent with the theory, as a displaced torpedo would have bulged the bomb bay doors, which wind resistance could then have pealed back – leading to a rapid increase in drag preventing the aircraft from gaining altitude at sufficient speed.
A significant amount of mud had accumulated within all landing gear bays, underneath the wings including flap surfaces, and over the fuselage towards the tail. They dragged sideways across the runway surface, causing that single track. The report doesn’t mention this but it is clear that the aircraft was well and truly stuck.
Most of the time, I would turn the floatplane setting the tails of the floats onto the shore in order to make our departure a simple matter of climbing in, starting the engine, and with a burst of throttle, sliding into the deeper water and going about our day. In short order, we loaded our gear and beat a hasty retreat back to Ketchikan.

The tail comes off the ground before you even realize the airplane is ready, climbs like a bat out of you know where, handles like its on rails, and can land almost anywhere in a matter of a couple hundred feet. But my recommendation is to find a very early Bonanza for your first V-tail experience.
Photo copyright Russell Munson] On April 26th, 1964 a radial-powered biplane with wings and tail in Champion Yellow and Stearman Vermillion-painted fuselage took off from an airfield near Lumberton, NC. “The steel fuselage frame, tail surfaces, and landing gear have been repaired as needed, media blasted, and primed.
The problem is that the aileron can only be deflected to a point after which the drag becomes significant. Most of the ailerons mass lies behind the hinge, making it tail-heavy. Tail-heavy ailerons droop downwards when they arent being pulled by the control system. potentially reverting the aileron back into a tail-heavy state.
And ice doesn’t just make things slippery, it messes with the airflow over the wings, cuts down on lift, and ramps up drag. Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. This leads to a serious loss of lift and an increase in drag. If you don’t act quickly, you’ll soon feel its effects.
However, this wasn’t the only unique thing about Cierva Twin; it was outstanding in its class for the following reasons – Coaxial Rotor System – This design eliminated the need for a tail rotor, reducing mechanical complexity and increasing lift efficiency. This allowed for more stability and control, especially in hover.
Increased lift on the raised wing immediately creates more induced drag. What’s induced drag? Induced drag is the resistance that happens as a result of creating lift, caused by swirling air around the wings that slows the airplane down. The higher drag on the raised wing reduces its speed relative to the lower wing.
From Delta Air Lines: Go behind the scenes with two teams who play a key part in the product strategy and engineering aspect of a nose-to-tail cabin redesign. Debuting on a narrowbody Boeing 757 aircraft that will begin flying on domestic and short haul international routes later this fall, followed by a widebody Airbus A350 in early 2025.
As air flows over it, a force like lift results, and the tail is pulled in the opposite direction of the deflection. But instead of an upward force of lift on a wing, it’s a horizontal force pushing the tail of the plane causing the nose of the plane to move left and right. This is called adverse yaw.
Notable design changes included the introduction of a swept tail design in 1960 and a new cowl design in 1961, which improved aerodynamics and performance. Micro vortex generators are also a popular upgrade, optimizing airflow over the wing and tail surfaces to enhance control.
Flying in clouds of cold and warm fronts can lead to very small supercooled water droplets which build up as rime ice on the parts of the aircraft exposed to the wind: probes, antennas, and the leading edges of the wings and tail. This signifies a significant increase in drag which is causing the airspeed to drop by 15 to 20 knots.
Gradually used to replace metals on parts of aircraft tails, wings, engines, cowlings, and parts of the fuselage, composites reduce overall aircraft weight and improve operational efficiency. Area Rule In the 1950s, NASA scientist Richard Whitcomb discovered several fundamental solutions to key aerodynamics challenges.
He was in his forties when we flew together in his V-tail Bonanza. I put the gear down one dot above the glideslope and let the drag bring the aircraft down at its 550 foot-per-minute descent rate. The Power Jockey. I could tell he was a good pilot. His skills were excellent, and his anticipation was admirable.
Staying in ground effect protects the glider from a stall because of lower induced drag. However, perhaps the safest response for everyone involved would have been the following: Rather than trying to climb with the tow plane, I should have stayed in ground effect while communicating the request for a greater airspeed.
MiGs on your tail! It felt like we were dragging an 18-wheeler truck! Functioning exactly as designed, those flat-plate boards sticking into the airstream were creating beaucoup drag, battling against the J-79s’ thrust. Four o’clock!” Break right! Break left! Frantically, I kept scanning the instrument panel, mind racing.
They were counted as they loaded up and sat between each other’s legs, facing the tail. Still facing the tail but now standing, they checked the gear of the jumper ahead of them, sounding off in the affirmative. On command, the stick stood as one, hooking in their static lines aft of where I was tethered. Air Force C-130.
Following D-Day, as the war began to tail off, Yeager returned to fly combat missions, as Eisenhower yielded to Yaeger’s demands. These helped to minimize drag and ensure aerodynamic efficiency at high speeds. Nevertheless, Yeager remonstrated this point with Supreme Allied Commander General Dwight D. Eisenhower himself.
However, the increased drag might make it impossible to take off again. Make sure not to pull back too hard, or you could cause a tail strike. This does two things: it keeps the load on the wings and increases drag. A soft touchdown can only do so much if the field is too muddy or has massive potholes.
Once Shmulik was in the pattern the key thing that possibly could have helped him (besides a greater altitude) is a very high airspeed to get out of the sink and safeguard against the sudden tail wind. If that happens, the propeller causes a lot of extra drag, comparable to half-extended airbrakes.
Innovative features like the Hybrid Laminar Flow Control (HLFC) system further enhance the Dreamliner’s fuel efficiency by reducing aerodynamic drag. The aircraft’s design, which includes advanced composite materials, contributes to significant weight savings and improved fuel economy.
A sideslip approach creates excess drag and requires more control inputs. But remember, the crosswind you just battled is still hitting the aircraft’s wing and tail. Preparing Your Approach Decide if you want to use the crab or the sideslip approach. The crab method is the most comfortable way to fly the approach.
Despite some engine troubles, the FJ-3 gained greater acceptance with the fleet than the FJ-2 and was later modified to carry the AIM-9 Sidewinder air-to-air missile as the FJ-3M and in 1956, the Navy retrofitted all its FJ-3s with refueling probes under the left wing to couple to a drogue dragged behind an aerial refueling tanker.
