METHOD OF DEFINING CAVITY DEPTH AT OPTICAL SURFACE OF VIEWING PORT OUTER GLASS OF MANNED SPACE VEHICLE |
摘要 |
FIELD: instrument engineering. ^ SUBSTANCE: method of defining cavity depth at optical surface of viewing port outer glass of manned space vehicle includes cavity stereo photography, measuring of distance from the centre of each stereo pair picture to the same point of cavity image. Also measurement of distance between lens axes for the first and the second shot, measurement of distance from lens main surface to the surface of viewing port inner glass and measurement of air medium pressure in pressurised section and in space between glasses. Cavity depth is calculated from the expression: ^ . ^ EFFECT: accurate definition of cavity (defect) depth of viewing port outer glass in flight conditions with required accuracy. ^ 2 dwg |
