After five months of production, I finally finished it - the LPE-IV launch vehicle
Thanks to the tower from IronManElonMusk
*Rocket Introduction
The LPE-IV is a two-stage rocket,
The first stage uses four FE-12 engines, takeoff thrust: 340t, fueled by liquid oxygen and methane
The second stage uses an FE-12V engine (a vacuum optimized version of the FE-12 engine), vacuum thrust: 1283kN, vacuum specific impulse: 385s, and fuel is liquid oxygen and methane
LEO(300km*300km)Transportation capacity:17t
See the figure below for details


In addition, I made some structures to make this rocket as close to a real rocket structure as possible


* Activation group
AG 1: Automatic launch program
AG 2: Water spray noise reduction
AG 10: secondary auxiliary power system
* How to use
1. Press AG 1 to start the launching program and enter the target data according to the pop-up window requirements ( All heights are in "meters". All angles are in "degrees". )
2. After the input is complete and the data has been confirmed, press AG 1 again to confirm the launch program
3. Wait for 5s
4. The program starts, wait and enjoy the launch process
Note:
I am not very good at vizzy, so the orbit accuracy is not very good, please forgive me

* Other versions

11571P LPE-IV Launch Vehicle Pro
Hope you enjoy it and have fun!

        453 ivansheppard8531.7 years ago@CentaurAerospace can u upload the FE-12V engine as a separate craft? I like the way the preburner exhaust goes into the nozzle instead of being dumped outside it.
