INFLUENCE OF THE PAWA-1 PASSIVE ARMOR MODEL OF THE HELICOPTER FUSELAGE MODEL AGAINST RPG-7 ON AERODYNAMIC CHARACTERISTICS
This paper contains results of experimental tests of the use of the PAWA-1 passive armor model as a protection of the helicopter fuselage model against PG-7 projectiles launched from RPG-7 hand grenade launcher. The influence of the PAWA-1 model on aerodynamic coefficients of the fuselage model of the Sokol, Polish helicopter, is shown. The research was carried out in wind tunnel on the helicopter test stand. Measurements of aerodynamic coefficients acting on the fuselage model with and without protection were taken with the use of six-component strain gauge internal balance placed inside the model of the fuselage for angles of attack α within-90 to 90 degrees range and for sideslip β. The influence of the installation of the PAWA-1 model on the helicopter fuselage model on static stability for entire range of angles of attack a is presented.
