Abstract
An acceleration force isolator assembly for attaching a payload, such as a spacecraft or satellite, to a launch vehicle wherein axial acceleration forces on the payload are attenuated. The attachment includes an upper interface ring that is secured to the payload and a lower interface ring that is secured to the launch vehicle. Flexure of the upper interface ring provides axial compliance when axial acceleration forces are transmitted from the launch vehicle.
Claims5
A vibration isolator for coupling a payload to a launch vehicle comprising upper and lower interface rings, the upper interface ring being attached to the payload, the lower interface ring being coupled to the launch vehicle;
- mounting pads coupled to the lower interface ring, the upper interface ring being secured to the pads at multiple circumferentially spaced locations;
- the payload being joined to the upper interface ring at circumferentially spaced locations between the multiple circumferentially spaced locations whereby the upper interface ring flexes in an axial direction thereby attenuating acceleration force distribution from the launch vehicle to the payload.
