Simulation of an airplane using Open VOGEL, an open source framework for aerodynamic simulations based in the UVLM. The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level.
In February 1976, work commenced to automate the methods contained in the USAF Stability and Control DATCOM, specifically those contained in sections 4, 5, 6 and 7.The work was performed by the McDonnell Douglas Corporation under contract with the United States Air Force in conjunction with engineers at the Air Force Flight Dynamics Laboratory in Wright-Patterson Air Force Base.

So if an aircraft's wing area is increased by 10% and nothing else is changed, the takeoff speed will fall by about 5%. Likewise, if an aircraft designed to take off at 150 mph grows in weight during development by 40%, its takeoff speed increases to 150 1.4 {\displaystyle 150{\sqrt {1.4}}} ≈ 177 mph.
Propulsive, aerodynamic, and gravitational force vectors acting on a space vehicle during launch. The forces acting on space vehicles are of three types: propulsive force (usually provided by the vehicle's engine thrust); gravitational force exerted by the Earth and other celestial bodies; and aerodynamic lift and drag (when flying in the atmosphere of the Earth or another body, such as Mars ...
In aerodynamics, the pitching moment on an airfoil is the moment (or torque) produced by the aerodynamic force with respect to the aerodynamic center on the airfoil . The pitching moment on the wing of an airplane is part of the total moment that must be balanced using the lift on the horizontal stabilizer . [ 1 ] :
x b axis - positive out the nose of the aircraft in the plane of symmetry of the aircraft; z b axis - perpendicular to the x b axis, in the plane of symmetry of the aircraft, positive below the aircraft; y b axis - perpendicular to the x b,z b-plane, positive determined by the right-hand rule (generally, positive out the right wing) Wind frame
Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.
