Method for correcting cruise fuel consumption characteristics based on hovering test flight data

Abstract

The invention discloses a method for correcting cruise fuel consumption characteristics based on circling test flight data. The method comprises the following steps of: a, selecting a height point, aspeed point and a flight state, and calculating the hourly fuel consumption during stable circling at different roll angles; b, carrying out oil consumption characteristic correction; c, calculating the hourly oil consumption of the engine through the function relationship; e, correcting to the target weight, which comprises circling oil consumption calculation and level flight oil consumption calculation; correcting the oil consumption per hour to a target weight level flight state through the performance data; the method comprises the following steps: calculating the hourly oil consumption of an engine, the hourly oil consumption of the engine and the oil consumption in a level flight state during different rolling stable circling; the flight test data can be analyzed and calculated at different speeds, cost-reduced oil consumption data can be reliably and accurately measured, Meanwhile, multiple groups of effective flight test data can be obtained by selecting multiple groups of stable circling with different roll angles and changing the angle of the stable circling.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a correction method for cruising fuel consumption characteristics based on circling flight test data. Background technique [0002] The fuel consumption characteristics of the aircraft cruising section have a very important impact on the aircraft's range and endurance performance, which is directly related to the accessibility of the aircraft's range and endurance performance indicators in the flight test. However, in the flight test stage, due to the constraints of the aircraft's production time , flight test cost constraints, and the number of flight sorties, the flight test data in the cruising segment is not enough to cover all the sample points of fuel consumption characteristics of the aircraft, resulting in a shortage of data in the analysis of fuel consumption characteristics, which affects the follow-up test flight plan and test flight progress. , in the fl...

Problems solved by technology

However, the previous methods have the following deficiencies: 1. The flight action is instantaneous, considering the error of the fuel sensor, it is impossible to accurately measure the fuel consumption during the execution of the action; 2. When performing the flight action, the weight of the aircraft is unique and cannot Efficiently acquire multiple sets of flight test data in the same flight
