Abstract

The utility model relates to the technical field of airplane hatch door design, in particular to a cargo door of an aircraft. The rear-opening cargo door comprises an upper hatch door and a lower hatch door, wherein the upper hatch door can be lifted up inwards, and the lower hatch door can be opened downwards. When the lower hatch door and a floor in a cabin are on the same plane, the lower hatch door can be used as a horizontal cargo bridge. When the lower hatch door is opened downwards, the lower hatch door can be used as an oblique cargo bridge, and the angle of the slope is within 15-17 degrees. The lower hatch door of the combined cargo door can be used as the cargo bridge, and the angle of the slope is within 15-17 degrees. Consequently, an air stair of the cargo door on the side face or a ground cargo bridge is replaced, and loading of cargoes becomes more convenient and safer.

Description

Open the goods door after a kind of aircraft compound type

Technical field

Aircraft door design field of the present invention particularly relates to a kind of aircraft goods door.

Background technology

Aircraft in existing CCAR23 section is the side design of opening the door, though wherein being arranged, many moneys transport plane can realize loading the LD3 standard container, in loading process, the variation of acting point is wasted time and energy loading process but the characteristics of opening the door due to side cause, and in carrying out the air-drop operation process, the personnel that disembark from the side direction opened door or goods all may threaten to lower horizontal tail position, bring safety hazard, and disembark personnel or goods under the visual field not good enough yet.And existing back pullout (BPO) design is applied to large transport airplane more, and size and weight are all very large, and is not suitable for CCAR23 section flivver.

Summary of the invention

The technical problem to be solved in the present invention:

By after open goods door design, realize the longitudinal load of flivver, not only can be quicker than a side handling goods that opens the cabin, and be more conducive to guarantee the safety of goods and aircraft platform in airborne air delivery operations.

Technical scheme of the present invention:

According to HB7465-96 " aircraft air transport pallet Netcom standard " and the requirement of GJB5194-2003 " military transportation airplane loading criterion " and the vertical stator channel of flivver of goods longitudinal load requirement definition;

Open the goods door after a kind of aircraft compound type, comprise and inwardly to dig the top hatch door, can open the bottom hatch door downwards; Wherein, the bottom hatch door with the cabin in floor during at same plane, can do horizontal goods bridge and use; When the bottom hatch door is opened downwards, can do inclination goods bridge and use, the slope is between 15 ~ 17 degree.

Beneficial effect of the present invention:

1) by after open goods door design, can realize the front deck carrying, rear deck cargo transport, especially for flivver, unit can be convenient to better and the collaborative of passenger exchanges, best passenger's flight experience and service is provided, is more conducive to the passenger and boards separating of passage and cargo channel, make handling goods quicker;

2) open cargo door after and make it possible to complete more safely airborne air-drop aerial mission.May be subjected to prominent wind effect to touch tailplane when both having avoided airborne personnel or goods deliver from vault, cause all situation generations of danger of people, machine, make again can use to waft when extreme low-altitude goods is delivered and drop, and do not need to have prevented that goods is in the undue rolling on ground with aircraft is static;

3) Xiamen of compound type cargo door can be made the goods bridge and uses, and the slope has substituted airstair or the ground goods bridge of side cargo door between 15 ~ 17 degree, makes the more convenient and safety of Container Loading.

Description of drawings

Fig. 1 is the utility model and uses view.Wherein, 1. 4. longitudinal load passage (level) largest enveloping 5. rear goods (upwards turning down to open position forward) 6. rear goods (off position) 7. rear goods Xiamen (goods bridge, turn down to open position backward downwards) 8. 9. goods bridge level attitude of rear goods Xiamen (off position) of visiting of visiting of ground printed line 2.LD3 freight container (goods bridge tilt load) 3.LD3 freight container (vertical equity loading).

The specific embodiment

The LD3 Container Dimensions is larger for less 23 aircrafts of CCAR of main cabin size, open after this type compound type cargo door structure can guarantee the LD3 freight container can be on ground goods bridge during without Ground Vehicle tilt to load, the horizontal longitudinal load in the time of can Ground Vehicle being arranged again.Thereby alleviate structural weight by reducing hatch door arm of force length, make it more to be fit to flivver; Open cargo door longitudinal load channels designs after flivver, make the cargo hold size satisfy LD3 container loading space, and satisfy the situation of verting in loading process; Rear body empennage fabricate block upwarps the aerodynamic optimization profile, satisfies the assurance that takes into account lift when loading needs.

Claims

1. An aircraft combined rear opening cargo door is characterized in that the rear opening cargo door includes an upper hatch that can be turned inward, and a lower hatch that can be opened downwards; wherein the lower hatch is in the same position as the cabin floor. When on the same plane, it can be used as a horizontal cargo bridge; when the lower hatch is opened downward, it can be used as an inclined cargo bridge with a slope between 15 and 17 degrees.
