Abstract
A linear translation thrust system for moving an object from one location to another that includes at least two platforms and pivotally connected members. The distance between one platform and the second is varied by inflating and deflating an inflatable bladder. The linear translation thrust system may also include a conduit for coupling the exhaust system of a vehicle to the interior of the bladder so that the exhaust pressure of the vehicle inflates the bladder.
Claims20
A linear translation device comprising:
- a base;
- a platform above the base;
- an intermediate platform between the base and the platform, the intermediate platform having an opening;
- an inflatable bladder between the base and the platform, the inflatable bladder passing through the opening in the intermediate platform for moving the platform away from the base during inflation of the inflatable bladder;
- at least one first hinge member having a first end pivotally connected to the base and a second end pivotally connected to the intermediate platform;
- at least one second hinge member having a first end pivotally connected to the platform and a second end pivotally connected to the intermediate platform.
