dc.description |
A high-pressure air feed system, suitable for use with blowing
models mounted on a six-component virtual-centre balance, is described.
Air is supplied to the balance by a flexible ring main feed so that no
air is lost as with an air-bearing system. Constraints on the balance
are very low; at an internal pressure of 30 p.s.i. gauge with a mass
flow of 0.5 lbs/sec. all force corrections were less than 1 lb., and the
pitching moment correction less than 0.5 lb.ft. Rolling and yawing
moment corrections were 2.0 lb.ft. and 2.7 lb.ft. respectively. The
constraints were measured using a calibrator Which enabled the desired
mass flow to be passed through the system without additional constraints. |
