Advanced UAV Aerodynamics, Flight Stability and Control: Novel Concepts, Theory and Applications Pascual Marqués, Andrea Da Ronch Advanced UAV aerodynamics, flight stability and control: Novel concepts, theory and applications presents emerging aerospace technologies in the rapidly growing field of unmanned aircraft engineering. An aircraft in straight-and-level unaccelerated flight has four forces acting on it. (In turning, diving, or climbing flight, additional forces come into play.)These forces are lift, an upward-acting force; drag, a retarding force of the resistance to lift and to the friction of the aircraft moving through the air; weight, the downward effect that gravity has on the aircraft; and thrust, the.

[2] Originally designed as a single-seat, nuclear-attack aircraft, a two-seat Wild Weasel. The Republic F Thunderchief, was a supersonic fighter-bomber used by the United States Air Force. The Mach 2 capable F bore the brunt of strike bombing over North Vietnam during the early years of the Vietnam War, and has the dubious distinction of being the only US aircraft to have ever been removed from combat due to high attrition rates.

For example, the mission specifications for the X pictured in figure came from a request for proposals from the U.S. Air Force Flight Dynamics Laboratory in which they were seeking a research aircraft that would explore the forward swept wing 6.

The forward swept wing idea resulted from the transonic test of an aft swept wing of a Grumman configuration which had been proposed to satisfy the NASA HiMAT RFP (request for proposal). The winning proposal was submitted by Rockwell, and the Rockwell HiMAT was built, flown, and is currently in the Smithsonian Air and Space Museum.

Military aviation forum mainly focusing on the F, F and F jet fighters. Contains high quality discussions and has a gentle but strict moderation. NASA tested the X, a forward-swept wing jet, back in the early 90’s and submitted their data, but a fighter aircraft was never produced.

Over the years since then certain areas of engineering have advanced and are now up to the task of supporting an aircraft featuring a forward-swept wing.

The aircraft was a swept wing monoplane. The wing and horizontal tail were tailored in order to keep the flow laminar over a large portion of the wing/tail area. The wing design benefited from an imposed negative pressure gradient over the largest possible length of local by: An aircraft's design may employ wing sweep to mitigate adverse effects in the transsonic and supersonic regimes.

When an aircraft with swept wings is side-slipping after applying a yaw, the relative wind on the outward wing will be more aligned with the chord line of the wing's cross section than the inward wing. Q&A for aircraft pilots, mechanics, and enthusiasts.

Visit Stack Exchange. The wing is tapered in two sections, with more taper on the outer 40% of the span. Such double taper plans can provide lift/drag ratios close to that of the ideal elliptical wing, and have benign stall characteristics.

The same holds for forward-swept configurations. The military scouting and trainer airplane SAAB MFI Safari was designed with an improved field-of-view in mind, which is why it features a shoulder-mounted wing with the main spar behind the two occupants.

The wing is swept forward to solve the CG issue that results from the engine and the two. They discussed theories about each part’s contribution to lift, drag, or control. They designed a course of parametric research to understand the strength or weakness of those theories.
