Thrust is a reaction force described quantitatively by Newton's third law. ... Aerodynamic force – Force exerted on a body as it moves through air or gas;
Also, the direction of the force of thrust is generally fixed in the body frame, though some aircraft can vary this direction, for example by thrust vectoring. The wind frame is a convenient frame to express the aerodynamic forces and moments acting on an aircraft.
The aerodynamic force on a powered airplane is commonly represented by three vectors: thrust, lift and drag. [3]: 151 [1]: § 14.2 The other force acting on an aircraft during flight is its weight, which is a body force and not an aerodynamic force.
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 ...
One technical definition is that a kite is “a collection of tether-coupled wing sets“. [119] The name derives from its resemblance to a hovering bird. [120] Kutta condition – is a principle in steady-flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies with sharp corners, such as the trailing edges of airfoils.
Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
F is the engine thrust; α is the angle of attack; m is the vehicle's mass; D is the vehicle's aerodynamic drag; L is its aerodynamic lift; r is the radial distance to the planet's center; and; g is the gravitational acceleration at altitude. Mass decreases as propellant is consumed and rocket stages, engines or tanks are shed (if applicable).
Internal aerodynamics is the study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a jet engine or through an air conditioning pipe. Aerodynamic problems can also be classified according to whether the flow speed is below, near or above the speed of sound.
