Research of fuel flow regression model of aircraft climb phase based on QAR

Abstract

Abstract:

QAR can be used for aircraft and engine performance analysis, recording abundant key flight data such as fuel flow. Taking PW4077D engine installed in B777-200 as researching object, the author analyzes its QAR data in details, builds fuel flow regression model during aircraft climbing phase with multiple regression analysis approach, and verifies the accuracy with actual data. The results build basis for comprehensive research of engine fuel flow controlling laws, help to monitor and predict engine fuel flow and improve aircraft safety and economy.

Key words: aircraft engine, fuel flow, regression model, QAR
