Description

I’ve had the idea for this design of engine for a few months now but I put it on the side while I worked on traditional prop planes and waited for 1.1 to launch. Today I put together a simple concept and this engine is basically 2 of those attached end to end with a few modifications. I think there is real potential behind these engines because of their relative efficiency compared to Props and the capability to now make scale jets such as Sabres and P-80s. HOWEVER its seems they will have a significantly higher part count and I found from my testing that speed increases don’t necessarily depend number of blowers, but more around the number of fan blades attached to the shaft and angle of blades. They also have a quite small diameter (3ish meters) and operate in very similarly to real life. I.E. Long spool up time, heavy, Efficient, higher operating speed.(potentially)

This model is more compact than my Kycoming XR-7755-K engine but it is much heavier and of a much higher part count.

SPECS

  1. Total Weight: 79 TONS
  2. Total Length: 18 meters
  3. Total Height: 6.4 Meters
  4. Total Width: 9.6 Meters (including sled)
  5. Max Lbs of Thrust SL: 67,346 lbs (Aprox) !!!!!!!!!!!!
  6. Max Speed(prototype): 40 m/s flat
  7. Blower Count: 48 Junos
  8. Blade Count: 16
  9. Fan Blade Count: 48
  10. Current Redline: 30-32 RAD/s no matter what

NOTES

  1. This type of engine is extremely reliable just from my initial tests and the axle sits in a 3 stage wheeled bearing.
  2. AZIMECH I want you to help me develop these. I’ll post in your thread at a later date, I don’t want to flood it with all my content and ideas.
  3. This engine type produces very little torque because it is so compact and there is very little stress on the drivetrain allowing for potentially very high RPM, like real life.
  4. A lot of my speculation on the potential for these engines is mainly guesswork, but we have almost maxed out the current Prop technology and wheel-less bearing engines seem to have to much friction to operate efficiently, so this seems more promising. For a prototype she has a great top speed (40 m/s) and I believe this could be improved with weight reduction and power increases.
  5. My design is modular and you can just copy sections onto one another, but it is unsustainable as you only get about a ¾ speed increase per section added and I think it exponentially declines in power until it is to heavy to function. I’m sure this can be improved.
  6. This is designed after real jet engine technology and it could be the next generation of KSP DIY engines. It also looks badass as shit.
