[Suzaku 3 officially released, stainless steel rocket, methane fuel, recyclable, 9 machines in parallel, 4.5 meters in diameter, road transportation, capacity of more than 20 tons] After the successful launch of Zhuque 2 Yao 3, the Blue Arrow official website officially disclosed the information of the Suzaku 3 rocket .
It is expected to be capable of first flight in 2025. This first flight in 2025 seems crazy, but this rocket is smart in that it has not changed the engine. It is just an improved version of the TQ-12 of the current Suzaku 2. What needs to be solved is The problem with the bold choice of stainless steel storage tanks is gone. SpaceX’s starships are currently overweight due to their use of stainless steel. Domestic companies that follow the stainless steel route will also encounter similar problems. The current Suzaku 2 may also have the problem of overweight structure, resulting in substandard transportation capacity. The subsequent Suzaku 3 will be switched to stainless steel, which can be said to be very brave and the challenge is not small.
The diameter of the rocket is 4.5 meters, so it is impossible to transport it by special train (it is said that it cannot be scheduled for a special train). According to legend, it has been transported by road from Hainan to Jiuquan. The diameter of the fairing is 5.2 meters (very large), and the entire arrow is 76.6 meters in diameter. It is equipped with 4 sets of grid rudders and 4 deployable landing legs.
The rocket uses Blue Arrow Aerospace’s self-developed Tianque series liquid oxygen methane engine. The first sub-stage uses 9 TQ-12B engines, and the second sub-stage is equipped with 1 TQ-15B vacuum engine. The take-off thrust is 900 tons, and the liquid oxygen methane propellant is
disposable. The mission’s low-orbit carrying capacity reaches 21.3t, the recovery mission in the navigation area reaches 18.3t, and the return recovery mission reaches 12.5t.
In the future, a rocket stage can be reused up to 20 times.
On the Month of October- November 2023 Zhang Changwu, founder/CEO of Blue Arrow Aerospace As a guest speaker, attend this conference event of Aerospace Information Industry International Ecosystem Event 2023 It has finally been officially announced that Blue Arrow has developed the reusable Carrier Rocket stainless steel Suzaku 3 rocket….
Many people did not notice the details on. Blue Arrow disclosed for the first time its Suzaku 3, which will succeed Suzaku 2 Carrier Rocket – Reusable Carrier Rocket. Launch vehicle.
Judging from the picture, the one-time launch to low-Earth orbit has a transport capacity of 20 tons, the recovery area is 16.5 tons (not necessarily at sea), and the return transport capacity is 11 tons. Two-stage design, stainless steel storage tank, the diameter should be more than 4 meters by comparison, and it is suspected that 7 engines (maybe 9) are stuffed inside. First stage with grille rudder with deployable landing legs.
The railway transportation limit made by the Shanghai Institute is 3.8 meters. If it is 4 meters higher, it is equivalent to killing the possibility of inland launch? Or is there another way? After all, Landspace Blue Arrow spent a lot of effort on the launch pad in Jiuquan Satellite Launch Center, Inner Mongolia, China, and People’s Republic of China. , so it is unlikely that they will be abandoned. What do you think?
Blue Arrow originally wanted to go to IAC for a press conference, but it was later cancelled for some reason. This time in China, it was taken the opportunity to release. There is nothing unexpected about the overall design. Perhaps the only exception is the use of stainless steel. It is the first mainstream private aerospace company in China to officially announce the use of stainless steel.
General Manager Changwu of Blue Arrow shared that no matter what, I have always recognized Blue Arrow’s hard work and development in the field of China’s commercial space launch vehicles, and I am grateful for its efforts and contributions to the commercialization of China’s launch vehicles. I will always believe in it. , as long as you keep working hard like this, @LANDSPACE Blue Arrow Aerospace will be realized sooner or later.
