Frictional and retarding forces on aircraft tyres.
Part III: planing.
This Data Item is Part III of a series dealing with frictional and retarding forces on aircraft tyres. Part I, ESDU 71025, introduces the subject, describes the basic mechanics of tyre-braking friction and contains the reference list for the whole series. Part II, ESDU 71026, gives a method for estimating tyre-runway braking force.
This Data Item considers planing of aircraft tyres on wet runways. Thus, it is complementary to ESDU 71025 and ESDU 71026 in so far as it treats situations where only a negligible tyre-runway coefficient of friction can be developed.
The objectives of the Data Item are threefold:
- to describe the observable characteristics of planing and the mechanisms which produce it,
- to present the available data relating to planing of aircraft-type tyres,
- to indicate the uses of these data for the prediction and analysis of planing.
This Data Item has been superseded by ESDU 15003.
