1st, take a flight test effective sortie Universal Criterion and rating

It is determined that effective sortie Universal Criterion of taking a flight test it is as follows：

FTVA >=[W] is effectively

FTVA ＜ [W] invalid (1)

In formula：FTVA refers to sortie effectiveness evaluation score value (or success rate) of taking a flight test, and [W] refers to sortie success rate thresholding of taking a flight test Value, generally takes [W]=0.6.

The rating of flight test effective sortie divides as follows：

Effective sortie is divided into：It is outstanding：FTVA >=90%；It is qualified：60%≤FTVA ＜ 90%；Part effective sortie^[note]：Extremely FTVAK >=60% of few one of flight test subject；Noneffective sortie：The FTVAK ＜ 60% of each flight test subject；In formula：FTVAK Refer to flight test subject success rate.

[note]：It is only applicable to " combined flight test sortie ".

The evaluation of flight test effective sortie is completed by evaluating flight test subject, the evaluation of flight test subject effectiveness Take a flight test action to complete by evaluation, and one is taken a flight test what action typically took a flight test parameter to characterize by one group.Therefore, it is Evaluation flight test subject, it is necessary to which the relevant parameter for choosing the action of taking a flight test in correspondence flight test subject is most basic as object is passed judgment on Element, should be chosen for completing the parameter of taking a flight test that certain sortie flight test subject plays a major role in principle.The flight test of one sortie Can be single section's purpose take a flight test, or multiple subjects composition combined flight test.

2nd, flight test subject success rate computing formula is as follows

In formula

The action number that n-flight test subject is included

p_kThe qualification rate of-k-th action, k=1 ..., n

q_kThe weighted value of-k-th action, and

q₁+q₂+…q_k+…+q_n=1 (3)

The weighted value of action of taking a flight test refers to that the examination of the action of taking a flight test, to completing the significance level of flight flight test subject, needs It is previously set.When being difficult to determine the degree of action performance assessment criteria importance of respectively taking a flight test, can adopt etc. power process method.

The evaluation of driver behavior qualification rate can refer to national military standard GJB 624A-2010《Military aircraft scientific research is taken a flight test training requirement》 In " evaluation criterion ".For the flight test subject for having clear and definite index request in test mission list, test mission list should be preferentially selected Specified in index.

Reach for same flight test subject requires repeatedly to take a flight test in test mission list and once requirement of taking a flight test Action, its effectiveness score of the examination is once defined by best.

3rd, sortie success rate computing formula of taking a flight test is as follows

In formula

FTVAK_iThe success rate of-i-th flight test subject, i=1,2 ..., m

Q₁+Q₂+…Q_i+…+Q_m=1 (5)

The flight test subject quantity that m-sortie of taking a flight test includes

The weighted value of each flight test subject depends on the importance and crucial journey of each flight test subject for decomposing in formula (5) Degree, needs to be previously set.Success rate FTVAK of each flight test subject is calculated by formula (2).

4th, sortie success rate of taking a flight test is calculated according to flare maneuver qualification rate as follows

This flight has n main flare maneuver element, and the qualification rate of each action element is p_Ai, shared by each action Weigh as q_Ai, then success rate FTVA of this flight_AIt is represented by

In formula

q_A1+q_A2+…+q_Ai+…+q_An=1 (8)

Power q of each action in formula (6)_AiIt is to be previously set according to the criticality of action, p_AiIt is to each action Acceptable level by being given after above-mentioned national military standard prejudgementing criteria analysis, if the action is excellent, p_Ai=1, the action is qualified, then p_Ai =0.6, the action is unqualified, then p_Ai=0.

Excellent P in formula (7)_Ai=1 is the upper limit for having taken good degree (0.9～1), qualified to take p_Ai=0.6 is to have taken conjunction The lower limit of lattice grade (0.6～0.9), unqualified p_Ai=0, take the lower limit of unqualified grade (0～0.6).So both it is easy to take Value, has certain reasonability again.

This flight success rate FTVA can be calculated by formula (6)_A, and substitute into take a flight test in effective sortie Universal Criterion formula (1), with Success rate standard [W] is compared, you can judge whether the sortie of taking a flight test is effective.

5th, sortie success rate of taking a flight test is calculated according to flight parameter qualification rate as follows

When flight is made up of a flight test subject, can be passed judgment on using flight parameter.Flight parameter pass judgment on form with Flare maneuver passes judgment on similar, only flare maneuver need to be transformed into into main flight parameter, uses FTVA_BRepresent that flight parameter is passed judgment on Flight success rate, then

In formula

p_Bi--- i-th flight parameter qualification rate

I --- flight parameter number, i=1,2 ..., n

q_Bi--- the power shared by i-th flight parameter

q_B1+q_B2+……+q_Bi+……+q_Bn=1 (11)

6th, type choosing method is passed judgment on

Judge type is chosen according to object is passed judgment on.Passing judgment on object has two layers of meaning：One refers to that this flight is single examination Winged subject or combined flight test subject, two refer to flare maneuver still with flight parameter as main judge object.

If single flight test subject, then choose flare maneuver and pass judgment on class pattern (6) or flight parameter judge class pattern (9) To calculate success rate FTVA, if combined flight test subject, then choose combined flight test subject and pass judgment on class pattern (4) to calculate successfully Rate FTVA；If using flare maneuver as main judge object, choosing formula (6), if using flight parameter as main judge object, Then choose formula (9).

Either choose flare maneuver and pass judgment on formula (6) or flight parameter judge formula (9), final judge object elements are all It is flight parameter, only formula (6) is that, using flare maneuver as main judge object, and formula (9) is commented as master using flight parameter Sentence object, in whole flight, flight parameter number is substantially constant after selecting, only in difference Flare maneuver in flight parameter emphasis it is different, play a crucial role to the action success or failure several are only selected in a certain action It is individual until one or two parameter, and mainly Quantitative evaluation.

Letting us choose up to see flare maneuver judge class pattern (6) still selects flight parameter to pass judgment on class pattern (9), and this wants concrete condition Concrete analysis.If taking based on aerial main actions segment data to pass judgment on sortie effectiveness of taking a flight test, it is proposed that select formula (6)；If Take one completely to rise and fall data to pass judgment on sortie effectiveness of taking a flight test, it is proposed that select formula (9).

7th, the determination method of element weighted value

Select and pass judgment on it is necessary to determine element number, elementary composition and element the weight ratio of passing judgment on object after type, this One process of sample is referred to as element power and determines.It is assumed that choosing flight parameter passes judgment on formula (9), then element weighting is determined as follows Value：

1) element number is chosen

It is flight parameter that flight parameter passes judgment on the judge object elements of formula (9), should be found out to complete the flight test subject task Those flight parameters for playing a major role.For each intensity flight test subject, these flight parameters are included but is not limited to： Flight speed (V), flying height (h), three-dimensional overload (n_z、n_x、n_y), the angle of attack (α), yaw angle (β), three-dimensional manipulate displacement (d_e、 d_a、d_r), three angle of rudder reflection (δ_e、δ_a、δ_r).The main flight parameter of the flight test subject should be found out from these flight parameters, typically For, preferably not more than 8.

2) determine elementary composition

Have chosen it is elementary composition it is necessary to determine after the param elements number of this flight, typically by key element, important unit Element and general element composition.Key element refers to the element played a crucial role to this flight success or failure, and key element number is few, but rises Pivotal role, important element is less, plays an important role, and general element is more, plays a secondary role.For example it is assumed that have selected 8 flying Line parameter then may be selected 1～2 key element as the element of this flight, 2～3 important elements, and remaining is general unit Element.

3) determine that element weights compare q_i

Determine it is elementary composition after weight ratio q of each element is determined by three ingredients of element_i, determine q_iShould abide by Follow following principle：

(1) determine that element is weighed by the significance level of element, than bigger, vice versa for more crucial element weights.

(2) power of most critical element is not more than 0.5, and the least power of important element is not less than 0.05.

(3) all elements power sum is equal to 1.

8th, element qualification rate obtaining value method

Every kind of element qualification rate p_iCan be with one of following methods come value：

1) extreme value is taken

According to national military standard, element qualification rate is divided into excellent, qualified and unqualified Three Estate, the value model of each grade Enclose and be shown below

It is so-called take extreme value and just refer to maximum (upper limit) or minimum (lower limit) are according to circumstances taken in each rate range, Excellent level takes its maximum p₁=1, regular grade and unqualified level difference minimalization (lower limit), i.e., regular grade takes p₂=0.6, no Regular grade takes p₃=0, such benefit one is convenient, and two is that each grade differential is obvious, there is certain reasonability.

2) treating excess syndrome border estimated value

So-called treating excess syndrome border estimated value, refers to by the practical situation in three qualification rate rate ranges choose estimated value, example Such as, certain element belongs to qualified grade according to the Changing Pattern and size of the parameter, occupies upper middle again in the rate range, i.e., Can use qualification rate p of the parameter₂For certain value between 0.8～0.9, p is such as taken₂=0.88；If occupying lower middle can use p₂ For certain value between 0.6～0.7, p is such as taken₂=0.62.Although this obtaining value method comparison is rationally, cumbersome.

Analyze according to more than, and with reference to the accompanying drawings 1, obtain concretely comprising the following steps for the present embodiment：

Step 1：Collection pilot fight parameter of taking a flight test, and judge this pilot fight be single flight test subject or Combined flight test subject, if combined flight test subject, into step 2, if single flight test subject, into step 3.

Success rate FTVAK of flight test subject is calculated according to below equation：

Wherein p_kFor the qualification rate of k-th action of the flight test subject, p_k∈ [0,1], n are the action that the flight test subject is included Number, q_kFor the weighted value of k-th action of the flight test subject, and q₁+q₂+…q_k+…+q_n=1；

Step 3：This pilot fight be single flight test subject, this pilot fight take a flight test sortie success rate FTVA according to Below equation is calculated：

Wherein p_AiFor the qualification rate of i-th action element of the pilot fight, p_Ai∈ [0,1], u are included for the pilot fight Action element number, q_AiFor the weighted value of i-th action element of the pilot fight, and q_A1+q_A2+…q_Ai+…+q_Au=1；

For example certain maneuvering flight sortie is made up of 5 major motor actions, action serial number k, each action and each The qualification rate of time period parameter testing corresponding to action is p_Ak, weighted value q shared by it_Ak, as shown in table 1.

The action qualification rate and action weighted value of table 1 certain maneuvering flight sortie

Action sequence number k	1	2	3	4	5
						Action qualification rate pAk	1	1	1	0.6	0.0
Action weighted value qAk	0.4	0.3	0.1	0.1	0.1

The effectiveness for calculating the maneuvering flight sortie is as follows：

FTVA=1 × 0.4+1 × 0.3+1 × 0.1+0.6 × 0.1+0.0 × 0.1

=0.4+0.3+0.1+0.06+0
