Carbon fiber composite brings infinite possibilities to UAV
When browsing the design of UAVs around the world, it is found that no matter what appearance or application, the only constant is the pursuit of lighter and stronger. Only in this way, UAVs can be competent for more tasks. In this context, the carbon fiber composite has become an important help to help UAV achieve the design against the sky.
Italy’s I.F.O company is exhibiting a concept manned multi rotor UAV, which looks like a UFO and can carry two people. The overall height of the aircraft is about 3M, the height of the cockpit is about 1.6m, and the width is about 2m. More spacious space to ensure the comfort of passengers in the UAV. Like most drones on the market, the vehicle uses electricity and is expected to fly for 60 to 70 minutes.
In order to land safely and stably, the UAV is equipped with six folding and shrinking legs, and damping equipment is installed on the legs. In case of emergency, the cockpit of the UAV can be separated from the fuselage, and the parachute can be ejected to ensure the safe landing of the cockpit.
The cockpit is designed with all carbon fiber, which can protect the passengers and reduce the weight of the UAV body. The fuselage is designed with eight rotors, with a maximum flight speed of 190 km / h. meanwhile, the designer said that the flight height can be comparable to that of the helicopter.
China: hydrogen fuel cell achieves 270 minute endurance
At the 13th Abu Dhabi International Defense Exhibition, hydrone-1800, a multi rotor vertical take-off and landing UAV jointly launched by AVIC technology import and Export Corporation and COBIT aviation, adopted advanced hydrogen fuel cell system, creating a new world record for 270 minute endurance of this class of UAV.
According to reports, hydrogen fuel cells have more obvious advantages. Compared with lithium battery, hydrogen fuel cell has less performance degradation, longer endurance and shorter filling time. In terms of power, hydrone-1800 adopts a 6-axis design, with a wheelbase of about 1.8m. It is made of all carbon fiber. It can realize industrial level three proofing (fire prevention, rain prevention and dust prevention). Even if a single propeller fails, it can land safely.
Hydrone-1800 hydrogen hybrid UAV has a maximum payload of 25 kg, a maximum flight radius of 100 km, and functions of ultra long distance image transmission, over the horizon remote control, precise positioning and navigation. It can be used for long-term cruise detection and industrial level survey, and can play a more important role in fire control, rescue and other fields.
Russia: small and solid circular integrated type
Aerodyne RC, a newly founded company in St. Petersburg, Russia, has developed a strong and incomparable UAV nimbus. This UAV inherits the blood of the fighting nation. Although its appearance is only the size of palm, it can be indestructible. Even if it is pressed by a car, it will not hurt a penny.
The most vulnerable parts of the UAV are the wing and wing arm, because once they collide with some objects or fall to the ground, the two parts will be damaged by different degrees of injury first. Nimbus adopts a round integrated structure fuselage. Although its rounded appearance lacks the cool temperament of edges and corners, it greatly ensures its flight safety. The carbon fiber material makes it more resistant to pressure, so as to ensure that it will not be broken in collision and falling.
In general, when a UAV is flying, it will lose a screw, a small part, etc. because these “organs” are designed outside, and any impact can’t stand it. The main electronic components and parts of nimbus are wrapped in the round fuselage, and no matter how bad the flight environment is, they are not afraid of damage.
France & Israel: a “paper plane” that can take pictures
The technology that combines VR and UAV, jointly launched by parrot, a French UAV company, and powerup toys, an Israeli company, brings a new play to the small paper airplane!
An ordinary origami plane, equipped with a front keel including a camera module, a carbon fiber bracket and a propeller, can completely transform the paper plane. Use the VR glasses box, put in the mobile phone, put it on, and you can start the flight show! Where people look, the paper plane will turn, and the pictures captured by the camera will be transmitted to the mobile phone in real time.
Compared with ordinary paper airplanes, FPV can not only watch the flight picture from the first angle of view, its maximum flight speed can be up to 32km / h, the flight time full of electricity can be up to 10 minutes, and the real-time return distance of the picture can be up to 91m!
No matter how the UAV pattern is renovated, as one of the five core subsystem technologies of the UAV system, the airframe is the most important basic support factor. Lightweight, long endurance, high load carrying capacity, and exchangeable standardized load module are the main target requirements that can drive the UAV system technology development at present. Lightweight is also the long endurance, high load The first condition of module standardization.
It is reported that although it has become a consensus in the industry to make UAV shell with carbon fiber materials, the application technology of carbon fiber materials also determines the level of UAV comprehensive performance, for example, the shell of carbon fiber UAV
Whether it is integrated molding, which is related to the lifting force, impact resistance and safety of the whole aircraft
It’s all directly related. In the future, the development of UAV will have higher technical requirements, and many composite enterprises are also striving for this.
