Torque is frequently applied to spacecraft, operating absent aerodynamic forces, by a reaction control system, a set of thrusters located about the vehicle. The thrusters are fired, either manually or under automatic guidance control, in short bursts to achieve the desired rate of rotation, and then fired in the opposite direction to halt ...
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 ...
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.
Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, structural analysis and manufacturing. The interaction between these technologies is known as aerospace engineering.
NASA testing a scale model Lockheed Electra in a wind tunnel for flutter. Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow.
The science of aerodynamics deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. The study of aerodynamics falls broadly into three areas: Incompressible flow occurs where the air simply moves to avoid objects, typically at subsonic speeds below that of sound (Mach 1).
John D. Anderson Jr. (born October 1, 1937) is the Curator of Aerodynamics at the National Air and Space Museum at the Smithsonian Institution in Washington, D.C., Professor Emeritus in the Department of Aerospace Engineering at the University of Maryland, College Park.
Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) was a NASA mission to test inflatable reentry systems. [1] It was the first such test of an inflatable decelerator from Earth-orbital speed. LOFTID was launched on an Atlas V 401 in November 2022 as a secondary payload, along with the JPSS-2 weather satellite. [2]
