摘要
Abstract
Correct engine characteristic map is basis of performance computation. Characteristic map of interpolation meth-od in many condition was discussed. For interpolation of internal work point zone,a new interpolation was introduced in the less data; spline interpolation was adopted in the more data. For interpolation of exterior zone, different work points were fitted based on LS method, required map was gained according to fitting law. When work point data was less, a new in-terpolation method was adopted to adding data by introducing unreal work condition, and interpolation was dealt with ac-cording to more data. Results was precise compared to factual value, it had reference value.关键词
