Static stability is the ability of a robot to remain upright when at rest, or under acceleration and deceleration Static stability may also refer to: In aircraft or missiles: Static margin — a concept used to characterize the static stability and controllability of aircraft and missiles.
Three cases for static stability: following a pitch disturbance, aircraft can be unstable, neutral, or stable. If an aircraft is longitudinally statically stable, a small increase in angle of attack will create a nose-down pitching moment on the aircraft, so that the angle of attack decreases.
Static stability: minimum distance from the center of mass (COM) to any edge of the support polygon created by the legs in stance for each moment in time. [13] A walking animal is statically stable if there are enough legs to form the support polygon (i.e. 3 or more) and the COM is within the support polygon.
The student must be able to go into the stable arched position out of the aircraft before being progressed to dummy ripcord pulls. Dummy ripcord pulls (DPs) – the student demonstrates the ability to pull a dummy ripcord while still using the static line to actually deploy the canopy. Generally the student must perform three satisfactory DPs ...
Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather is in equilibrium with its environment.
Posturography is the technique used to quantify postural control in upright stance in either static or dynamic conditions. Among them, Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of ...
Its role is the training of General Duty Pilots (GDP), Aeronautical and Avionics Engineers and the initial training of other Ground Branch cadets. Cadets join the academy following a recommendation by the Inter Services Selection Board (Pakistan) and the AHQ (PAF) Special Selection Board for Short Service Commission candidates.
A static fire test includes a wet dress rehearsal and adds the step of firing the engines at full thrust. [3] The engine(s) are fired for a few seconds while the launch vehicle is held firmly attached to the launch mount. This tests engine startup while measuring pressure, temperature and propellant-flow gradients, and can be performed with or ...
