neutral stability — Two situations when there is neutral stability in atmosphere: (a) when environmental lapse rate (ERL) = dry adiabatic lapse rate (DALR) and air is dry and (b) when ELR = saturated adiabatic lapse rate (SALR) and air is saturated. i. In… … Aviation dictionary

stability — is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure. Note: passenger vehicles exhibit varying characteristics depending upon test conditions and… … Mechanics glossary
Stability derivatives — are a means of linearising the equations of motion of an atmospheric flight vehicle so that conventional control engineering methods may be applied to assess their stability.The dynamics of atmospheric flight vehicles is potentially very… … Wikipedia
Neutral Beam Injection — In order to initiate a sustained fusion reaction, it is usually necessary to use many methods to heat the plasma, including RF heating, electron cyclotron resonance heating (ECRH), ion cyclotron resonance heating (ICRH), and neutral beam… … Wikipedia

Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes … Wikipedia
Relaxed stability — In aviation, relaxed stability is the tendency of an aircraft to change its attitude and angle of bank on its own accord. An aircraft with relaxed stability will oscillate in simple harmonic motion around a particular attitude at an increasing… … Wikipedia
relaxed static stability — The operation of an aircraft at the center of gravity aft of the neutral point where the airplane has a negative static margin. The neutral point is that point along the path of the center of gravity movement where the stick force per knot drops… … Aviation dictionary
Plasma stability — An important field of plasma physics is the stability of the plasma. It usually only makes sense to analyze the stability of a plasma once it has been established that the plasma is in equilibrium. Equilibrium asks whether there are net forces… … Wikipedia
