Problems solved by technology

Its disadvantages are: there are many subjective factors, and the accuracy of the evaluation results is poor.
And the evaluation results can only give a relative comparison, not the degree of difference in the effectiveness of the helicopters

Embodiment Construction

[0028] 1. Sorting the transportation efficiency and capability of the same type of helicopters: select 4 helicopters of the same type to participate in the transportation task, and sort the 4 helicopters in descending order according to the expert review method: J1, J2, J3, J4

[0029] 2. Carry out the simulation test of helicopter transportation tasks: the number of helicopters participating in the simulation test is n=4, and carry out the simulation test of helicopter transportation tasks according to the test outline: the total transportation volume is 1000 kg, the set range is 200 kilometers, the cruising altitude is 5500 meters, and the field temperature is 25 ℃, field height 4500 meters

[0030] 3. Determine the weight value of a group of transportation efficiency indicators:

[0031] 3.1 Obtain the evaluation index of helicopter transportation efficiency: see Table 1.

[0032] model Cruise speed(km / h) Load capacity M1(kg) Round-trip flight time T1(h) A...

Abstract

The invention belongs to a helicopter assessment technology and relates to a method for determining transport task index weights of helicopters. The method for calculating the transport task index weights of the helicopters is characterized by comprising the following steps of performing transport performance capacity sorting of helicopters same in type; performing transport task simulation experiments of the helicopters; determining a group of transport performance index weight values; determining effective index weight values; and determining a transport performance index weight range. According to the method for determining the transport task index weights of the helicopters, provided by the invention, subjective factors are reduced and the accuracy of an assessment result is improved; and not only relative comparison but also difference degree of helicopter performance can be given.

Description

technical field [0001] The invention belongs to the helicopter evaluation technology and relates to a method for determining the index weight of a helicopter transportation task. Background technique [0002] At present, the method of determining the weight of helicopter transport task indicators is the expert evaluation method, which focuses on the role of expert knowledge in performance evaluation. The process is generally: select the characteristic index that can best reflect the performance of the helicopter, score it by a group of experts, and finally obtain the performance value of the helicopter by processing the opinions of the experts. When this method is used for program evaluation or combat capability evaluation, an evaluation consistency test must be carried out. Because it is carried out by comparing two factors, if there are too many factors, there may be contradictory evaluations. In addition, the comprehensive expert evaluation method also needs to solve th...
