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.
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 ...
is the static margin and must be negative for longitudinal static stability. Alternatively, positive angle of attack must generate positive yawing moment on a statically stable missile, i.e. must be positive. It is common practice to design manoeuvrable missiles with near zero static margin (i.e. neutral static stability).
[citation needed] A positively stable aircraft will also resist any bank movement. A Cessna 152 is an example of a stable aircraft. Similarly, an aircraft with neutral stability will not return to its original attitude without control input, but will continue to roll or pitch at a steady (neither increasing nor decreasing) rate.
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 ...
The Pakistan Air Force Academy Asghar Khan (PAFAA) [a] is an accredited four-year military academy which provides undergraduate education to officer candidates of the Pakistan Armed Forces, primarily the Pakistan Air Force (PAF).
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.
