FORCE AND MOMEMENT BALANCE AND SUPPORT THEREFOR

摘要

This invention relates to a force and moment balance (1) including a support (9) therefor and more specifically, but not exclusively, to a force and moment balance (1) and a support (9) therefor for a wind tunnel. Force and moment balances are known in the art and are typically used in wind tunnels to measure the force and moment loads on a model in the wind tunnel. A problem with current balances is that there is inherent vertical movement associated with horizontal force. According to the invention, the balance (1) has a fixed end (3) and a movable end (6) with a number of supports (9) between the fixed end (3) and the movable end (6). Each support (9) includes compensation means to compensate for resultant movements caused by lateral movement of the movable end (6) relative to the fixed end (3).

主权项

1. A support for a force and moment balance comprising:
a first end and a second end; and a support structure between the ends; the support structure including:
a first support member extending from the first end;a second support member extending from the second end;an intermediate member between the first and second members; andbiasing means for biasing the members such that lateral movement of the second end causes relative movement between the members and neutralizes relative longitudinal movement between the second end and the first end.
