FIELD: machine building. ^ SUBSTANCE: proposed test bench comprises foundation with central opening, vertical frame, simulator of aerodynamic effects with spring unit mounted on vertical frame, simulator of excess pressure in aircraft fuselage with power exciter and thrust element. Aircraft hatch cover is mounted above foundation opening and connected via rocker with spring unit. Said cover is articulated, from below, with cover opening power air cylinder and simulator of excess pressure in aircraft fuselage. ^ EFFECT: testing covers to open at aerodynamic drag and internal excess pressure. ^ 7 cl, 6 dwg |
