| Summary: | The longitudinal stability of the UAV of the container start of the aerodynamic scheme "tandem", at the start from the transport container, is studied. Modeling by the methods of computational aerodynamics shows that such a UAV is unstable at angles of rotation of consoles to 60 ° and stable - at large angles of rotation. In the full-scale experiment it was established that in the range of exit velocities 12 ... 14 m / s, take-off masses of UAV 1.8 ... 3.1 kg, the rate of configuration change during the time 0.2 ... 0.3 s longitudinal stability is ensured during the transition from transport to cruising configuration. |
