Pneumatic or air isolators

• Natural frequency range: 1.5 – 3 Hz
• Examples:
  • Air Springs: Available for maximum 20kN
  • Flexible Bellows: Maximum working pressure 7 bar & force 45kN
• Ideal arrangement of air spring: The narrowest distance between the mounting points of satellite over the air spring (top plane of air spring) should be at least twice the height of the centre of gravity above plane of springs.
• Benefits:
  • Low Maintenance Cose
  • Freedom of fatigue
  • Range of temperature operation ( -50 to 110 degree celsius)
• Limitations:
  • Since the system is inherently soft, precaution must be taken to ensure stability.
  • The main limitation to the use of these isolators is reliance on elastomers which are prone to wear and tear due to friction.
