    sudden rise, sudden change
    (резкое изменение параметров)
    - уплотнения — shock wave, shock
    резкое повышение давления. плотности, температуры газа (воздуха) и уменьшение его скорости при встрече сверхзвукового потока с каким-либо препятствием. — abrupt changes in supersonic field of flow, through which the fluid undergoes decrease in velocity and marked increase in pressure, density, temperature.
    - уплотнения, внешний — external shock wave
    - уплотнения, внутренний — internal shock wave
    - уплотнения, входной — inlet shock wave
    - уплотнения, головной — blow shock wave
    скачок уплотнения, возникающий перед телом, — а shock wave in front of a body,- such as an airfoil, or apparently attached to the forward tip of the body.
    - уплотнения, замыкающий — terminal shock wave
    - уплотнения, косой — oblique shock wave
    скачок уплотнения, поверхность которого образует с направлением набегающего сверхзвукового потока сжимаемого газа острый угол. — а shock wave inclined at an oblique angle to the direction of flow in a supersonic flow field.
    - уплотнения, неприсоединенный — detached shock wave
    скачок уплотнения, не имеющий общей точки с породившим его телом. — а shock wave not in contact with the body which originates it.
    - уплотнения, присоединенный — attached shock wave
    скачок уплотнения, имеющий общую точку, с породившим его препятствием (передней кромкой аэродинамического профиля, носовой частью тела) при сверхзвуковом потоке. — an oblique or conical shock wave that appears to be in contact with the leading edge of an airfoil or the nose of а body in а supersonic flow field.
    - уплотнения, прямой — normal shock wave
    скачок уплотнения, поверхность которого перпендикулярна направлению набегающего потока, выбивание с. уплотнения поглощать с. уплотнения — а shock wave perpendicular, ог substantially so, to the direction of flow in a supersonic flow field. shock expulsion swallow shock (wave)
