Description
Technical Field
The invention relates to the technical field of air-drop vehicles, in particular to a hanging type aerial containerized vehicle for parachute-free air-drop.
Background
In the aspect of air-drop modes, the existing air-drop modes are mainly divided into air-drop with umbrella and air-drop without umbrella. The air-drop with umbrella is the main air-drop type at present, and the air-drop System mainly includes a Low speed air-drop conveying System (LVADS), a Low Altitude Parachute System (LAPES), a Joint Precision air-drop System (JPADS) developed in recent years, and the like. Among them, low speed air drop transport system (LVADS) is most commonly used, and generally drops the cargo from the airplane flying at low speed at low altitude not more than 1000 m, the cargo leaves the airplane under the traction action of the parachute, and the parachute provides the deceleration and slow landing action in the vertical direction during landing, thereby ensuring that the cargo completely lands; the low-altitude parachute landing system (LAPES) is characterized in that a transporter is airdropped in an ultra-low altitude state (generally, the height of the transporter is not more than 5 meters), a parachute is thrown out of a rear door of a cabin, the goods are mainly pulled out of the cabin by the pulling force of the parachute in the horizontal direction to achieve deceleration and release of the goods, the downward impact force of landing of the goods is basically buffered by the structural design of a bottom tray, a recoil rocket is mounted on the bottom tray, the goods are ignited at a moment before landing to reduce the impact force, and an aluminum alloy chassis with a honeycomb structure can further absorb the final impact and finally land smoothly; the JPADS is an air-drop system based on a global positioning system, and an airplane can accurately air-drop various goods packages with different sizes by using parachutes from high altitudes of 7600 m, so that the supply requirements of ground troops are met. Under special conditions, the mode of the parachute-free air-drop is occasionally used, but the parachute-free air-drop is limited by the packaging structure design, the packaging and the buffering material technology, so that more conditions are required to be met, firstly, the air-dropped goods must be of a variety which is not easy to break, and the weight cannot be too large; secondly, the transport means must be dropped at the ultra-low altitude and low speed, the general dropping height is not more than 20 meters, the limit dropping height is not more than 50 meters, and the vehicle is dropped under the condition of hovering (zero speed) of the carrier aircraft; thirdly, the package must have good anti-falling and shock-resistant capabilities.
In terms of air-drop vehicles, there are mainly 3 types of cargo vehicles for air freight, namely, package boards, containers, and vehicle frames. The container plate is mainly an aluminum flat plate, net buckles for fixing the net cover are arranged on the periphery of the container plate, the middle of the container plate is slightly recessed, and after goods are placed on the container plate, the container plate is wound by a thin film and is covered with the net cover for fixing; the container is a closed box made of aluminum plates, which is more favorable for protecting goods; the frame is mainly used for transporting special cargos such as vehicles. The container plate and the goods carried by the container can be airdropped, the airdropped container mainly uses the airdropped container with an umbrella under the non-special condition, the container for the airdropped container needs special design, the airdropped container generally uses a wooden or aluminum box in the early period, the airdropped container is widely used along with the development of the plastic industry because of light weight and low cost, the airdropped container with better quality can also be used for direct airdropped without umbrella drop, but generally only tens of kilograms of goods can be loaded and used below 20 meters, otherwise the integrity of the container body and the goods cannot be ensured.
In summary, the existing various air-drop equipment has some obvious disadvantages, including:
1. the parachute drop air-drop system is complex in structure, multiple in steps and long in time in the preparation and delivery process, and the timeliness requirement of agility guarantee is difficult to meet;
2. the parachute is greatly influenced by weather and air current, the air drop dispersion range can reach hundreds of meters or even thousands of meters, and the parachute is not easy to find and use;
3. the parachute has a large target and long dead time, and is very easy to be found and knocked down by enemies in wartime to cause damage to airdropped goods and materials;
4. the air-drop height of the parachute-free air-drop carrier is too low, the flight safety of the airplane is difficult to ensure,
5. the air-drop mode of the rear cabin door has long duration, the gravity center of the airplane is continuously changed, and the requirements on the performance of the airplane and the operation level of a pilot are high.
