Description
Technical field
The present invention relates to military airfields and military-civil airport planning technical field, especially a kind of military airfield single flight road
Training capacity evaluating method.
Background technique
One, the concept of military airfield single flight road training capacity
In civil aviation field, this concept of capacity of runway is the development with portfolio and puts forward, and is defined as
The maximum that unit time inner track can be run is taken off the sortie that lands.The general weighted average for using institute's organic type runway service time
Value indicates:
In formula: C is runway capacity；
E [T] is runway average service time；
PijIt is j type airplane tail with the probability of i type aircraft；
TijTime interval when for j type airplane tail with i type aircraft, between them.
Can be seen that its capacity from the concept of civil airport runway capacity is to be based on proposing under aircraft continuous operation state
, such as runway capacity is 30 sorties/hour, refers to the sortie of the continuous landing of aircraft in 1 hour.
In recent years, it with the development of military training demand, is also opened in the problem of military airfield planning field runway capacity
Beginning is studied.However the concept of civil airport runway capacity has apparent unworthiness for military airfield.Firstly,
Military airfield aircraft type in field, quantity are relatively fixed, unlike commercial air flights aircraft type, quantity are not fixed；Secondly, civil aviaton flies
Machine, which takes off, is added after course line destination of flying to, and military aircraft is then trained in the periphery Ben Chang airspace, the aircraft stagnant sky phase
Between, although remaining at closed state without aircraft on runway；Third, for runway, civil airport is in continuous clothes
Business state, and military airfield is then in discontinuity service state.
Its runway of primary study training capacity is answered, may be defined as: running in conjunction with the feature of military airfield based on above-mentioned difference
Road can ensure the training mission amount that air arm completes in 1 year, can simplify the year sortie of taking off and landing for that can ensure aircraft.
Two, the thinking of military single flight road training Capacity Assessment
The leading thinking of military airfield single flight road training Capacity Assessment is when counting to go off the course the maximum utilization being capable of providing
Between and flight training required for the time, the two is compared, obtains the year maximum sortie of taking off and landing that 1 year inner track is capable of providing.
Three, the determination principle of runway year pot life
Runway pot life is mainly influenced by meteorologic factor, runway integrity both sides, the amount difference for needing to count
It is as follows:
1. the meteorological condition clear for flying time in runway year
According to the division methods of aeronautical meteorology, by meteorological condition between daytime simple meteorological condition, complicated meteorology item between daytime
Four kinds of part, night simple meteorological condition, night IFR conditions situations, under four kinds of weather conditions, corresponding satisfaction can fly
The capable time is the meteorological condition clear for flying time in runway year.
2. the time required to guaranteeing runway integrity
Maintaining work required for runway integrity mainly includes two aspects: runway maintenance and runway trimming.Runway dimension
Before the shield time refers to flight every time, need to reserve regular hour progress runway maintenance, after reaching requirement, Cai Nengkai
Begin to fly；The runway trimming time refers to that runway in use for some time, is locally damaged, and influences flight safety, needs
Close the time that runway carries out the repairing of road face.
3. year runway pot life
Year runway pot life is that meteorological permitted hours subtract runway maintenance and trimming time.
Four, the determination principle of training required time
Training required time is that air arm organizes the time required for annual training.For some type, annual training is appointed
Can clearly there be i trained topic (i=1,2 ..., n) in business, complete each topic and be required to the corresponding time, by these times
It is accumulative, so that it may to count annual training required time.
According to the habit of military airfield flight statistics, is stated using " accounting for field time " and complete each topic to duty runway
Time demand, is defined as: open the time (deduct flight waiting time) flown to terminating using airport flight day.It is anti-to account for field time
The overall efficiency of flight tissue is answered, it is short to complete to account for field time used in same training topic, illustrates overall efficiency height, then on the contrary
Then the time is longer, and overall efficiency is low, illustrates in the presence of the delay in similar civil aviaton.
In recent years, military airfield is newly-built, is often faced with such problems in reorganization and expansion, can a runway, which meet, works as
Preceding army's requirement or a runway maximum are able to satisfy the training requirement in field of how many aircraft, currently for the problem
Answer an only answer qualitatively, fuzzy, the method for lacking theoretical foundation and calculating verifying.
It would therefore be highly desirable to propose a kind of military airfield single flight road training capacity evaluating method.
Summary of the invention
The invention aims to solve the deficiencies in the prior art, a kind of training of military airfield single flight road is provided and is held
Appraisal procedure is measured, opens up and theoretical foundation and calculation method is provided for single flight road Capacity Assessment and double course.
In order to achieve the above objectives, the present invention is implemented according to following technical scheme:
Train capacity evaluating method in a kind of military airfield single flight road, comprising the following steps:
S1, statistics are quasi- to account for field time KT with what type corresponded to that each trained topic is averaged every airplanei, i expression training session
Mesh, i=1,2 ..., n；
S2, the quasi- each trained topic of type of statistics respectively between daytime complexity between simple, daytime, night is simple, night is complicated
Deng the proportionality coefficient α for accounting for field time under four class meteorological conditionsij, i expression training topic, i=1,2 ..., n；J=1,2,3,4 is corresponding
It is complicated between simple, daytime between daytime, night is simple, night complicated four classes meteorological condition；
S3, statistics meteorological condition clear for flying runway year, T timeIt is meteorological, by complicated between simple between daytime, daytime, night is simple,
The corresponding license of night four class meteorological conditions of complexity is formed with the flight time, is respectively indicated are as follows: t '1、t’2、t’3、t’4；
The average time t that runway prepares before S4, statistics year fly5, annual runway trimming time t6With annual flight play
N；
S5, from TIt is meteorologicalThe annual runway of middle deduction prepares, the trimming time, obtains complicated, night letter between simple, daytime between annual daytime
It the available flight time under single, night complicated four class meteorological conditions, respectively indicates are as follows: t1、t2、t3、t4；
S6, use type Annual Training Duty according to quasi-, count between annual daytime it is complicated between simple, daytime, night is simple, night is multiple
Field time ZT is accounted for needed for all topics under miscellaneous four classes meteorological conditiont1、ZTt2、ZTt3、ZTt4；
S7, between complicated simple daytime, daytime, night is simple, accounts for field time needed for night complicated four classes meteorological condition and can
Determined with the time, decision rule is as follows:
If:
ZTt1≤t1, illustrate simple meteorological condition between daytime in requisition for the field time that accounts for meet requirement, it is on the contrary then illustrate
Runway is unable to satisfy requirement, need to open up double course；
ZTt2≤t2, illustrate IFR conditions between daytime in requisition for the field time that accounts for meet requirement, it is on the contrary then illustrate
Runway is unable to satisfy requirement, need to open up double course；
