Description
Technical Field
The invention relates to the technical field of airdrop carriers, in particular to a hanging type aviation container carrier for parachute-free airdrop.
Background
In the aspect of the air drop mode, the existing air drop mode is mainly divided into an air drop with an umbrella and an air drop without an umbrella. The airdrop with umbrella is the main airdrop form at present, and the airdrop system mainly comprises a low-speed airdrop conveying system (LVADS: low Velocity Airdrop Delivery System), a low-altitude parachuting system (LAPES: low Altitude Parachute Extraction System), a joint precision airdrop system developed in recent years (JPADS: joint Precision Airdrop System) and the like. The low-speed air drop conveying system (LVADS) is most commonly used, goods are generally thrown out from an airplane flying at a low speed at a low altitude of not more than 1000 meters, the goods leave the airplane under the traction effect of a parachute, the parachute provides a deceleration slow descent effect in the vertical direction in the landing process, and the goods are ensured to fall well; the low-altitude parachute landing system (LAPES) is characterized in that a conveyor performs air drop under an ultra-low altitude (usually not more than 5 m high) state, a parachute is thrown out from a rear door of a cabin, the pulling force of the parachute mainly pulls out cargoes from the cabin in the horizontal direction to realize the speed reduction and the throwing of the cargoes, the downward impact force of the landing of the cargoes is basically buffered by a bottom tray structural design, a recoil rocket is arranged on the bottom tray, a percussion part is ignited before landing, the impact force is reduced, and an aluminum alloy chassis of a honeycomb structure can further absorb the last impact and finally land smoothly; the combined accurate air drop system (JPADS) is an air drop system based on a global positioning system, and an aircraft can accurately drop various goods packages with different sizes from a parachute for high altitude up to 7600 meters, thereby meeting the supply requirements of ground troops. Under special conditions, an umbrella-free air drop mode is occasionally used, but is limited by the packaging structural design, packaging and buffer material technology, and the umbrella-free air drop needs to meet more conditions, firstly, the goods to be dropped are not easy to break and the weight cannot be too large; secondly, the transport means must be thrown at an air condition under the ultra-low altitude and low speed, the general throwing height is not more than 20 meters, the limit throwing height is not more than 50 meters, and the transport means is usually thrown under the hovering (zero speed) condition of the carrier aircraft; thirdly, the package must have good anti-shatter and anti-shock capabilities.
In the aspect of air-drop vehicles, there are 3 main cargo vehicles for air freight, namely, a pallet, a container and a frame. The container plate is mainly an aluminum flat plate, net buckles used for fixing the net cover are arranged on the periphery of the container plate, the middle of the container plate is slightly concave, and after goods are placed on the container plate, the container plate is wound by a film and covered with the net cover for fixing; the container is mainly a closed box made of aluminum plates, which is more beneficial to protecting goods; the frame is mainly used for transporting special cargoes such as vehicles. The container board and the goods carried by the container can be air dropped, the container for air drop needs special design under non-special conditions, the air drop box is generally made of wood or aluminum in early stage, the rotational molding air drop box is widely used along with the development of plastic industry due to light weight and low cost, and the air drop box with better quality can also be used for direct air drop without parachute, but can only be used for loading tens of kilograms of goods and under 20 meters, otherwise, the box body and the goods cannot be guaranteed to be intact.
In summary, there are some obvious disadvantages of the existing various airdrop devices, including:
1. the parachute air drop system has a complex structure, and the preparation and delivery processes have multiple steps and long time, so that the timeliness requirement of agility guarantee is difficult to meet;
2. The parachute is greatly influenced by weather and air flow, the air drop scattering range can reach hundreds of meters or even thousands of meters, and the parachute is not easy to find and take;
3. the parachute has larger target and long dead time, and is extremely easy to be found and knocked down by enemy in the war to cause the damage of air drop materials;
4. the airdrop height of the parachute-free airdrop carrier is too low, the flight safety of the airplane is difficult to ensure,
5. the mode of the rear cabin door air drop is long in duration, the gravity center of the aircraft is changed continuously, and high requirements are placed on the performance of the aircraft and the pilot operation level.
