Researchers at New Zealand's Rocket Lab stated that although space technology has been developing for many years, we still feel a bit like cavemen playing driftwood when entering space. In order to realize the goal of “annual launch number of satellites†breaking 100, and to send small satellites into thousands of orbits at an early date, the company came up with an interesting way – for example, the cost of replacing a carrier rocket with a traditional one is almost 1 /10 of the "battery-powered engines."
The liquid rocket engine's appetite is too large. It takes a lot of propellant every second of its flight. In order to "feed" it, the rocket needs to deliver propellant through the turbo pump to the engine's combustion chamber.
In conventional designs, people usually let gas turbines drive centrifugal or axial turbine pumps. Of course, we must admit that since the first rocket turbo pump was developed in the 1940s, they have all worked well so far.
But its shortcomings are also obvious, because it is too complicated to make the heavy fuel system work. Rocket Lab came up with a good idea to build a simpler lightweight "Rutherford" liquid fuel rocket engine.
