    stability
    (самолета)
    способность самолета самостоятельно уменьшать разности между возникшим под действием возмущения отклонением и предшествующим ему движением. — the property of an aircraft to maintain its attitude or to resist displacement, and, if displaced, to develop forces and moments tending to restore the original condition.
    -, аэродинамическая — aerodynamic stability
    -, боковая (поперечная) — lateral stability
    -, боковая (динамическая) — lateral-directional stability
    способность самолета самостоятельно устранять возникающие под действием возмущения боковые движения (скольжение, крен, рыскание). — the stability of those motions (side-slipping, rolling and yawing) which occur out of the plane of symmetry.
    -, боковая статическая способность самолета сохранять или восстанавливать равновесие статич. моментов крена и рыскания. — static lateral-directional stability
    -, динамическая — dynamic stability
    способность самолета после отклонения от исходного установившегося прямолинейного режима полета, вызванного действием возмущения, демпфировать колебания восстанавливающих моментов и плавно возвращаться к исходному положению. — the characteristics of an aircraft that causes it, when disturbed from an original state of steady flight or motion, to damp the oscillations set up by restoring moments and gradually return to its original state.
    -, коррозионная — corrosion resistance
    -, курсовая — directional stability
    - на водной поверхностиwater stability
    -, нейтральная — neutral stability
    способность самолета, находящегося в к-л режиме установившегося движения, легко переходить в другой режим также установившегося движения (не возвращаясь к исходному без вмешательства летчика). — the property of an aircraft in steady flight, to readily accomplish transition to another steady flight condition (not returning to the original state with the pilot not interferring with the aircraft control).
    -, ограниченная — limited stability
    - пограничного слояboundary layer stability
    - пo кренуrolling stability
    -, поперечная — lateral stability
    устойчивость в полете к возмущениям относительно продольной оси, т.е. возмущениям, вызывающим крен или боковое скольжение. — stability with reference to disturbances about the longitudinal axis of an aircraft, i.e. disturbances involving rolling or side-slipping.
    - поперечная (по крену)rolling stability
    - поперечная статическаяstatic lateral stability
    способность самолета при нейтральном положении элеронов автоматически устранять возникший при скольжении крен, или крениться в сторону, противоположную скольжению. — the static lateral stability is shown by the aircraft tendency to raise the low wing in а side-slip with the aileron controls free (or neutral).
    - по рысканиюyaw stability
    - по скоростиspeed stability
    - по тангажуpitch stability
    - потокаflow stability
    - пo углу атакиangle-of-attack stability
    - при скольженииside-slipping stability
    -, продольная — longitudinal stability
    способность самолета самостоятельно устранять возникающие под действием возмущения продольные движения в вертикальной плоскости. — the stability of those motions (vertical and forward motions and pitching) in the plane of symmetry.
    -, продольная статическая — static longitudinal stability
    -, путевая — directional stability
    способность самолета восстанавливать устойчивое путевое равновесие моментов рыскания, бокового скольжения. — the property of an aircraft to restore itself from a yawing or side-slipping condition.
    -, путевая статическая — static directional stability
    способность самолета с освобожденным или зажатым рулем направления сохранять устойчивое путевое равновесие. — the static directional stability (as shown by the tendency to recover from a skid with the rudder free) must be positive for any landing gear and flap position and symmetrical power condition.
    -, собственная — inherent stability
    -, статическая — static stability
    способность самолета восстанавливать нарушенное равновесие под действием стабилизирующих (восстанавливающих) аэродинамических моментов. — if the static margin is positive, the aircraft possesses static stability, and in general will not diverge when disturbed from a trimmed speed.
    -, флюгерная — weathercock stability
    изолированная путевая статическая устойчивость самолета, т.е. способность самолета сохранять или восстанавливать путевое равновесие (моментов рыскания). — the tendency to turn into the relative wind as determined by the change in aerodynamic moment about the center of gravity with change in wind direction, used for motion either in pitch or yaw.
    потеря у. (ла) — loss of stability
    потеря у. (конструкции, работающей на сжатие) — buckling
