| 摘要： | A new formulation fluid is proposed for use as the reference fluid for aerodynamic testing and qualification of commercial aircraft deicing and anti-icing fluids. The new formulation fluid is to replace the currently used reference fluid, MIL-A-8243D, which allows for large variation in its composition. The MIL-A-8243D fluid, manufactured up to 2005, is no longer commercially available because its chief user, the United States Military, now uses qualified commercial Society of Automotive Engineers deicing and anti-icing fluids. The new formulation fluid, a mixture of 68%propylene, 20%tripropylene glycol, and 12%demineralized water, is chemically compatible with current glycol-based fluids. Furthermore, it can be produced more simply and accurately than the more complex military (MIL) formulation it replaces. Having the same viscosity as MIL-A-8243D, the new formulation reference has been found to be essentially aerodynamically indistinguishable from the MIL fluid in validation test runs in which both fluids were tested with a candidate fluid for high-speed ramp aerodynamic standard qualification. The measurements and validation testing accomplished in the present study support the adoption of the new fluid for use as the reference fluid for the high-speed ramp standard aerodynamic qualification test in place of the current MIL fluid. An investigation similar to the one described in this report could establish if the new fluid also can be used as the reference fluid for the low-speed ramp standard aerodynamic qualification test. |
