Calculation method of shaft power and its uncertainty of turboshaft engine under small environmental deviation
The performance processing method of turboshaft engine high altitude simulation test was studied.The shaft power calculation method of turboshaft engine was studied and the calculation formula of shaft power under the condition of small deviation of environment simulation was derived by using small deviation and traditional similarity conversion theory.The experimental results showed that under the condition of small deviation,the calculation error of this method was 0.2%-0.6% lower than that of similar conversion.The formula of converted shaft power and the formula of uncertainty under the condition of small deviation were given.The shaft power calculation method and uncertainty calculation method proposed can provide a technical reference for relevant engineering and technical personnel.
