Rainbow-4 UAV replacing heavy oil engines' first flight successfully

According to news from Aerospace Technology Group Aerospace Rainbow UAV Co., Ltd., the space -time long -air sailing heavy oil drone independently developed by aerospace rainbow drones has completed scientific research tests not long ago. This type of drone has successfully completed test subjects such as autonomous take -off and landing, flight point flight, full -load transportation, maximum lifting, and flight hours.

On the basis of Rainbow-4, this type of drone replaces the heavy oil engine, which can be said to be the "upgraded version" of Rainbow-4. New drones can meet the needs of "higher flying, longer space, better safety".

The new drone adopts a national heavy oil piston engine, which marks one step ahead of the Rainbow drone towards domesticization. Experts introduced that heavy oil is one of the crude oil extracts, which are characterized by large molecular weight and high viscosity. The proportion of heavy oil is generally 0.82 to 0.95, and the thermal value is 100,000 to 11000 kcal/kg. Its ingredients are mainly hydrocarbons, and contain some sulfur and trace inorganic compounds.

Shi Wen, chief teacher of the Rainbow Series, explained that the rainbow-4 replacement heavy oil engine has special significance:

First, this time it has been replaced with an aviation oil engine with complete independent property rights. It is advanced and entered into a first -class ranks. It is an autonomous development, independent property rights, and domestic production of aviation engines. , Advantages of wide -area application environment.

Second, the drone uses a new type of aviation oil engine. The short-term time increases significantly, the range is farther, the cruise height and the lifting limit are higher, and the load capacity can also increase by 30%-50%.

Third, the flying capacity and load capacity of the drone platform have been greatly improved, which can be used for high -resolution on -site observation, surveying and mapping, communication, airline exploration, environmental monitoring, forest fire prevention, etc.

The successful completion of this test marks that this drone officially moves towards the market. After being put into use, this type of drone can fly complex environments such as plateau islands and broaden the application scenarios of drones. Smart cities and other injecting vitality. (Finish)
