   Rocket manufacturers announce new blueprint

ChinaRocket, the commercial aerospace division of China's leading rocket manufacturer, China Academy of Launch Vehicle Technology, announced plans to develop a variety of launch vehicle models to enter the space launch market.

The company announced on Saturday that its researchers are designing two types of solid propellant launch vehicles: Smart Dragon 2 and Smart Dragon 3; and at least one liquid propellant type, the Flying Dragon 1.

The SD-2 has a height of 21 meters, a diameter of 2 meters and a take-off weight of 60 metric tons. It is capable of transporting 500 kilograms of payload to a 500-kilometre sun-synchronous orbit. Flight testing will begin next year.

With a total length of 31 meters, a diameter of 2.6 meters and a take-off weight of approximately 116 tons, the SD-3 will be able to deliver more than 1.5 tons of cargo to the same track. Its first flight is expected to take place in 2021.

China Rocket President Tang Yagang said at a news conference in Beijing that the company will strive to achieve annual output of 10 SD-2 and 8 SD-3 to meet the needs of the rapidly growing commercial aerospace industry.

The SD-1 is the first in the series and the youngest member of the Chinese carrier rocket family. It first flew from the Jiuquan Satellite Launch Center in northwestern China in August and successfully sent three satellites to the Earth about 550. Kilometers of track.

The mission gave China's fourth carrier rocket brand, consisting of the China Aerospace Science and Technology Group's Long March series, China Aerospace Science and Technology Industry Group's fast boat and SQX (made by private space startup iSpace in Beijing).

The SD-1 is 19.5 meters high, 1.2 meters in diameter and weighs 23.1 tons. The rocket can place multiple satellites weighing 200 kilograms in a sun-synchronous orbit 500 kilometers from the ground. It is China's smallest and lightest launch vehicle.

Tang said that the SD series is designed to provide commercial satellite companies with reliable, convenient and economical launch services to build their networks or test their equipment.

The FD-1 will be a reusable medium-lift liquid fuel rocket. Currently in the detailed planning stage. Designers expect rockets to carry medium and large satellites, or several small satellites. He said that the first flight plan was to be carried out in 2021.

In another development, iSpace is China's first private company to complete its orbital mission. Last week, it said it was designing a reusable rocket that would be the country's first rocket made by a private company.

The SQX-2 has a height of 28 meters, a diameter of 3.35 meters and a take-off weight of approximately 90 tons. It will be able to send 1.9 tons of satellites to low Earth orbit, or send 1.1 tons of payload to 500 km of sun-synchronous orbit.
