Terminal velocity equilibrium conditions of a parachute with a limited range of dynamic stability
Języki publikacji
Abstrakty
W artykule omówiono sposób obliczania parametrów ustalonego opadania spado- chronu o ograniczonym zakresie stateczności. Przedstawione zostały nieliniowe równania równowagi sił i momentu pochylającego, których rozwiązanie pozwala wyznaczyć te pa- rametry. Wykonano obliczenia, które pozwoliły ocenić wpływ charakterystyk aerodyna- micznych oraz parametrów masowo-geometrycznych na możliwość uzyskania stanu rów- nowagi przez układ spadochron-ładunek.
In the article, the way of calculating parameters of stable descent of a parachute with limited dynamic stability was discussed. By solving nonlinear equations of balance of forces and pitching moment the above mentioned parameters can be calculated. The calculations, which enabled to determine the impact of aerodynamic characteristics and mass-geometric parameters on the possibility of obtaining the equilibrium in the para- chute – load system were made.
