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.
A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1]
The wind frame is a convenient frame to express the aerodynamic forces and moments acting on an aircraft. In particular, the net aerodynamic force can be divided into components along the wind frame axes, with the drag force in the −x w direction and the lift force in the −z w direction. Mnemonics to remember angle names
Takeoff weight components. The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
The aerodynamic forces are generated with respect to body axes, which is not an inertial frame. In order to calculate the motion, the forces must be referred to inertial axes. This requires the body components of velocity to be resolved through the heading angle () into inertial axes. Resolving into fixed (inertial) axes:
The rudder, and to a certain extent the ailerons via the use of bank angle, are the only aerodynamic controls available to the pilot to counteract the asymmetrical thrust yawing moment [citation needed]. The higher the speed of the aircraft, the easier it is to counteract the yawing moment using the aircraft's controls. [8]
It is useful for predicting aircraft handling, aerodynamic loads, stalling etc. = where ρ is actual air density and ρ 0 is standard sea level density (1.225 kg/m 3 or 0.00237 slug/ft 3). EAS is a function of dynamic pressure:
Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
