Resource Detailed View


  • Responsible Thematic Node: Small Bodies, Dust, and TNOs
  • Short Name: Hypervelocity impact facility
  • Brief description: CISAS Hypervelocity Impact Facility is based upon a two-stage Light-Gas Gun (LGG), that can achieve a very high shot-repetition-rate
  • URL: http://cisas.unipd.it/gen_ipervelocita.php
  • Type: CONTACT/Facility
  • English Language: YES
  • Restricted access: NO
  • Comment on the access:

  • Longer description:
    CISAS LGG can launch both solid cylinders and sabots at a maximum velocity of 6 km/s. Sabots are separated by means of aerodynamic drag in the flight chamber and can carry projectiles in the diameter range 0.4 - 3 mm.
    LGG MAIN PERFORMANCE
    Speed range 0.3 - 6.0 km/s
    Projectile mass 150 mg @ 6 km/s
    500 g @ 300 m/s
    Shot frequency up to 10 shots/day
    Barrel diameter 4.76 or 6 mm
    Barrel length 1.5 - 2.5 m

    The facility is equipped with diagnostic equipment such as:
    - projectile speed meaurements; - photographic system for 4 shadowgraphies (to image the impact event an the debris cloud) ; - acceleration measurments; - impact flash detection and characterization

    Different fields of application, as esample:
    - Impact experiments of planetary sciences
    - Spacecraft Disturbances due to Hypervelocity Impact (under ESA contract)
    - Test on CFRP panels (in collaboration with NAL-JAXA)
    - Test campaign for MPLM (logistic module of ISS)
    - Impact tests on tethers
    - Test on ceramic foams
    - Support for space instrument validation and qualification tests
