SIMULATION OF PARACHUTE DYNAMICS
|
| |
|
Summary :
|
|
SMALL RETURNABLE ORBITAL PAYLOADS OR SPACECRAFTS NEED SAFE, EFFICIENT AND AFFORDABLE RECOVERY SYSTEMS. SYSTEMS BASED ON PARACHUTES ARE THE MOST RELIABLE CHOICE DUE TO ITS PROVEN RELIABILITY AND LOW COST. THE DYNAMICS OF HIGH PERFORMANCE PARACHUTES AS PART OF A GROUND RECOVERY SYSTEM FOR SMALL RETURNABLE ORBITAL PAYLOADS HAS BEEN EXTENSIVELY INVESTIGATED. THE PRESENT WORK DEALS WITH THE MODELING AND SIMULATION FEATURES OF A HIGH PERFORMANCE GROUND RECOVERY SYSTEM BASED ON PARACHUTES, AND CONSIDERED MAINLY MODELING AND SIMULATION FEATURES OF THE SYSTEM. THE PROPOSED DYNAMIC MODELS COMPRISE AN ELASTIC PARACHUTE WITH APPARENT AIR INFLUENCE. THE ARTICLE PRESENTED THE MATHEMATICAL DESCRIPTION AND THE NUMERICAL SOLUTION OF THE PARACHUTE DYNAMICS DURING ITS MOTION ALONG A TRAJECTORY. THE METHOD TOOK UNDER CONSIDERATION SPECIFIC FEATURES, SUCH AS WAKE RE-CONTACT AND PARACHUTE ELASTICITY.
A VERY GOOD AGREEMENT BETWEEN THEORETICAL RESULTS AND EXPERIMENTAL DATA COULD BE ACHIEVED IN THE PRESENT WORK. THE PAPER SHOWS AND DISCUSSES THE RESULTS OF THE SYSTEM MOTION SIMULATION AND TESTS. |
