Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
As shown in Figure 1, the invention discloses a kind of high speed air route circle mouth configuration and dispatching method thereof, first design high speed air route circle mouth, then based on this high speed air route circle mouth, the aircraft being entered high speed air route by it is dispatched.
Step 1, design high speed air route circle mouth.
High speed air route circle mouth configuration comprises flight Accreditation Waiting Area, transitional region and reserved area;
Described flight Accreditation Waiting Area is column three layers of buildings, waits for entering main air route, be connected by transitional region with described reserved area for aircraft;
Described flight Accreditation Waiting Area is parallel with main air route, is more than or equal to default minimum allowable distance threshold value apart from the distance in main air route;
Described transitional region enters main air route for guiding aircraft;
Described reserved area connects with main air route, carries out the adjustment of side velocity for aircraft.
As shown in Figure 2, first a flight Accreditation Waiting Area S is set at the circle mouth starting point place of side, high speed air route, S is a multicolumn body structure, its top layer Accreditation Waiting Area W1 and main air route are positioned at same height layer, then the side that is connected with circle mouth in high speed air route arranges one section of reserved area S3, and reserved area S3 is connected by transitional region S2 with Accreditation Waiting Area S.Just can enter transitional region S2 when aircraft executes wait routine, move to reserved area S3, regulate the speed, import in the main air route in high speed air route.
Step 1-1: the distance D1 determining the structure of Accreditation Waiting Area S, place height layer and relatively main air route.
The high speed air route height layer that FAA provides is arranged between FL300-FL390, accordingly, FL370 height layer can be selected to arrange main air route, and Accreditation Waiting Area uses three height layers, is respectively FL370, FL360, FL350, Accreditation Waiting Area W1 and main air route are positioned at sustained height layer, and Accreditation Waiting Area W2 is arranged on FL360, Accreditation Waiting Area W3 is arranged on FL350, and every one deck arranges at most a frame aircraft to perform wait routine.
In the present invention, high speed air route is a unidirectional wall scroll air route, has fixing width, main air route width 20km, each 10km in center line both sides, and both sides, air route arrange the protected location of 10km more respectively, and reserved area width is equal with main air route width, are 20km.Therefore, Accreditation Waiting Area is apart from main air route one lateral extent D
1>=10km.
Step 1-2: determine the length of zone of transition S2 and the angle α with main air route thereof.
(1) during actual motion, all aircrafts entered in high speed air route have identical flying quality, and aircraft flight time in zone of transition S2 is equal and state is identical, do not exist each other and surmount behavior.But when designing, consider that the flying quality of different aircraft i there are differences, flying speed Vi is different, ti difference working time (i=1,2,3....) required in zone of transition S2, v
k=max{v
ithe length of therefore S2:
L
2≥L′
2＝v
k×t
k
(2) conveniently aircraft turns to remittance reserved area S3 from transitional region S2, and the angle in S2 district and main air route can be set to α=45 °.Therefore the length of S2:
Comprehensively above-mentioned (1) (2) two point:
The length L2 of S2:
Ｌ
２≥max{L′
2，L″
2}
Step 1-3: the length determining reserved area S3.
After aircraft enters reserved area S3, after the T2 time adjusts, remain a constant speed longitudinally motion, with a1 first even acceleration D/2 distance (D=20km) in side direction, then with the even deceleration D/2 distance of-a1 (a afterwards
1> 0) just arrive main center line of the airway, namely pass through again
time, change aircraft and just enter in main air route, namely a frame aircraft exists
can leave reserved area in time, therefore reserved area S3 length can be set to:
Operation demand can be met, aircraft speed when V1 is high speed air route actual motion.
Step 2: for the type circle mouth, determine its dispatching method.
Step 2-1: determine clearance condition.
What the present invention relates to is wall scroll high speed air route, and air route exists multiple aircraft sailed on the conventional air route of circle confession along the line and enters, and can be considered identical process, and do not consider the impact of upper-level winds for the motor behavior of aircraft in multiple circle mouth.In the present invention, aircraft changes is by the process of reserved area S3 to the transition of main air route, in one plane carries out, thus when only need consider to import longitudinal separation for the impact of security of operation.Therefore, the present invention is when setting up collision model, if the span of aircraft λ y represents, separation standard in longitudinal direction is S χ, centered by aircraft, respectively with 2S χ in longitudinal direction and lateral, 2 λ y fictionalize a rectangular area as collision slab, as shown in Figure 3.A, B represent the collision slab of two frame aircrafts in main air route respectively, and its length and width are all respectively a=2S
x, b=2 λ
yin order to avoid clashing, remain that A, B do not contact.Therefore, aircraft, when importing main air route, keep its collision slab not contact with the collision slab of front and back aircraft in main air route.
When there is aircraft execution wait routine in Accreditation Waiting Area, the position of aircraft in the main air route of Real-Time Monitoring, and pass to Accreditation Waiting Area controller, after elapsed time T0, arrived starting point place of S2 district by clearance aircraft C, just enter S3 district completely with the speed V1 flight T1 time, direction is parallel with main air route aircraft velocity reversal, again through a regulation time T2, implement to change, first even acceleration T in C aircraft side direction
3/ 2 times are even deceleration acceleration T again
3/ 2 times, when ensureing to enter main air route, side velocity is zero, and follow-up execution wait routine aircraft repeats said process, and determine whether to let pass, T3 is the Zong Huan road time.
According to above-mentioned motion process, the remittance of C aircraft divides following two kinds of situations:
(1) C aircraft imports main air route from A aircraft afterbody, as shown in Figure 4, guarantee that aircraft imports safety, and the distance L1 at A aircraft collision slab afterbody distance circle mouth O point place need meet following condition:
S
A＝V

0+T
1+T
2+T
3]
S
A+a-L
1-a≥a+V
1(T

3)
Therefore on main air route, a reference point M is set up in distance O point a distance, and OM length is V
1(T
0+ T
1)-a.
(2) C aircraft imports main air route from B aircraft front portion, and as shown in Figure 5, guarantee aircraft security of operation, the distance L2 at B aircraft collision slab front distance circle mouth O point place need meet following condition:
S
B＝V
1[T
0+T
1+T

3)-a
Therefore on main air route, a reference point N is set up in distance O point a distance, and ON length is V
1(T
0+ T
1).
Therefore, determine whether a frame aircraft lets pass, as long as judge in main air route, whether adjacent two frame aircrafts are positioned at outside MN leg, can implement to let pass to Accreditation Waiting Area aircraft.
Step 2-2: determine Accreditation Waiting Area aircraft scheduling implementation step.
1st step: when Accreditation Waiting Area of flying exist wait for enter the aircraft in main air route time, obtain in main air route the position of the aircraft flying to air route circle mouth, and judge it whether on MN leg;
2nd step: if the aircraft in main air route is all positioned at outside MN leg, then start during t=T0 to let pass, otherwise, continue to wait for until MN leg does not exist aircraft;
3rd step: entered S2 district by clearance aircraft and the uniform motion T1 time enter S3 district, and keep speed V1 to run.
4th step: enter S3 district aircraft, through a regulation time T2, start to carry out changing, in longitudinal direction, maintenance speed is constant, with the even acceleration of a1 in side direction
time, then with the even deceleration of-a1
time, complete and change.
