Started working a couple days ago on the systems and components that will be simulated by the computer.
A couple significant changes from the UD-4L we all know and love:
- Butterfly tail design was replaced with a T-tail similar in scale to the C-17
- Turbojets have been replaced with EDF and waveguide plasma
- Ramrockets have integrated with the EDF nacelles and replaced with toroidal aerospikes
- Vectored thrust has been integrated at the exhaust end of the nacelles (swivel)
Most of the changes were due to the theater we are operating in. Venus has no oxygen to make the turbojet/ramjet/scramjet beneficial so we transition straight from turbofan to rocket operations on ascent.
Currently, we are looking at 3 hydraulic loops with 2 pumps and 1 reservoir each and 2 coolant loops with 1 pump and 1 reservoir each. The 2 coolant loops exchange heat with the cryogenic fuel and oxidizer respectively.
