It’s real cool

ohhhhhhhhhhhhhhhhh ok that makes sense, sorta

@XjayIndustrys
Yea the Concorde did have intake ramps. VCE doesn't mean it has an intake ramp. The F-15 has intake ramps but it doesn't use VCE engines. A VCE is a special type of engine that can physically configure various parts of the engine for different flight profiles.

Yeah I’ve got this Bush plane and I’ve done more research then building lol

Cool I don’t really know what to say
The Concorde had ramps I think

@XjayIndustrys
I'm not sure if the Concorde used a VCE-like engine. I know it's engines were very fuel efficient at high speeds for it's time. Yea the SSTO is gonna be pretty epic, and incredibly complex. The SSTO is just my first step on space-related builds. I eventually want to make a giant space plane inspired by the Arkbird and the Rockwell Star-Raker concept. My giant space plane would have 2 variants, a space-station-oriented version that could act as an ISS replacement, and a militarized version that would be armed with a railgun and a laser turret for ICBM defense and orbital bombardment, however it could also be used to clean up space junk (like the Arkbird) and could also defend Earth against large asteroids.

@XjayIndustrys
Indeed I did. One thing I love about these builds, is that I actually do quite a bit of research on the roles and design aspects my build, so I'm actually learning some new stuff every time I do a build.
Sure I'll tag you, and thanks!

So the VCE is like the concords engines but a whole lot better and afterburning?
And it’s gonna go it a swweewwttttt spaceship
Cool
Very cool

Wow did u type all that?
That’s like more then 10words...
It is also very interesting
Tag me on any builds u want upvoted cause you deserve a reward for that amount or research and typing
I’m proud of you
That’s weird

Well so much for keeping in classified information...

@XjayIndustrys
The SSTO will seat 6-8 astronauts with a payload bay behind the crew compartment, and the rest of the space behind the SSTO would be used to store the fuel. The rocket fuel would be stored in the aft-section of the fuselage while the jet fuel for the VCTR system would be stored in the wings. It's gonna be interesting to see how it will all fold-out because The SSTO is going to be pretty big, and I'm worried it will become too heavy for the VCTR to provide enough thrust efficiently. If the VCTR system turns out to be a disappointment, we'll just switch to having the SSTO be powered exclusively by the linear aerospike engine. IDK we'll see. I have a lot on my plate for September and October so progress on any of my SP projects have been very slow.

@XjayIndustrys
The whole point of Rainier's SSTO is to not only function as a spacecraft, but to function as a regular air-breathing aircraft in the atmosphere. Not only that, but it would use the VCTR system for the majority of the climb to get into orbit, and when the VCTR system starts lacking in thrust as oxygen begins to dwindle as it leaves the atmosphere, the linear aerospike kicks in and pushes the SSTO during the rest of the climb into orbit. This is to save as much rocket fuel for the aerospike as possible. So when in the atmosphere, the SSTO uses the air-breathing jets, and when out of the atmosphere/in orbit, it uses the aerospike rocket engine.

@XjayIndustrys
But for the SSTO, Rainier's ramjet-ADVENT engine would be coupled with a separate/independent ramjet at the bottom of the nacelle which you see in the diagram. So the SSTO's VCTR engine system altogether will use x2 VCE turbofans, x4 ramjets (including the smaller ones at the top of the VCE engines), and x1 linear aerospike rocket engine at the rear-center of the SSTO.

@XjayIndustrys
While the YF120 is dead, General Electric revived the VCE concept with their new ADVENT engine. While not a fully-commissioned jet engine (just an experimental prototype/demonstrator engine), in the realms of my RP, Rainier Aerospace partners with GE and contributes to the development of the ADVENT engine so Rainier can use it on our future 6th generation fighter jets, possible SST's, and of course the future SSTO & mega-space-plane. However Rainier plans to take the ADVENT a step further and using an intake duct at the top of the engine, it pulls more air and compresses it (using the venturi effect I guess?) right before it's directed into the afterburner stage where it rapidly expands with the already powerful thrust of the turbofan and the afterburner. It's the same effect used on the SR-71's J58 where air is pulled from the cold compressor stage and re-routed to the afterburner. This not only provides excellent cooling for the engine but provides even more thrust for the engine to produce. Rainier's version of the ADVENT concept would feature a "ramjet" mode. The intake duct at the top of the engine would essentially act as a ramjet.

@XjayIndustrys
The Banshee utilizes a "variable-cycle-engine" (VCE) which is an afterburning turbofan jet engine that can change the airflow going into the engine to optimize it for maximum power and efficiency. The SR-71's J58 could be considered a VCE. General Electric made one of the first true VCE's, the YF120 during the ATF competition in the 90's and it would have powered either the F-22 or F-23. I don't know if it flew on a YF-22, but I do know the 2nd YF-23 prototype, PAV-2 aka "Grey Ghost" was powered by the GE YF120 and it performed much better than the Pratt & Whittney F119-powered PAV-1.

A VCE can optimize/adapt according to the speed and flight conditions for maximum efficiency and power. At subsonic speeds, it acts like a high-bypass turbofan bringing lots of efficiency as majority of the air is going through the fan/bypass instead of the core. But when it goes supersonic, it changes into a low-bypass turbofan configuration to provide much more power.

@XjayIndustrys
Oh it's gonna be a looong time before this thing gets built, but I'm gonna make the Banshee powerplant before the SSTO so I'll tag you when I release the Banshee.

Ooohhh and a tiny rocket thing in a Venturi
*edit tag me

Yay concord style engines in sp
“Does happy dance”
Yayayayayyayaya
Mining awaaayyy, ohhhhhh mining awwwwwwwwayyyyyyy!!!!!!!! Ohhhhhhhhhh baby I’m just MMIIINNNNIIINNNGGGG AAAAWWWWWAAAAYYYYYYY

@AdlerSteiner
Thanks, it's a 2D side-view of the left side of the engine.

I can’t tell if that’s a side view or a somewhat 3d. But good drawing!
