    That's one way to do it..... :) If you are still a bit of d-V short, you might try adding another Mk-3 tank to the shuttle, but that will disturb the CoM/CoL balance, so some tweaking would be neccessary afterwards

    The way I got around not having enough fuel is just build the shuttle with the capability to hold tonnes of fuel and then just fill up enough to finish the mission so I don’t have weight imbalance during the glider phase

    and if I have to haul a heavy payload, i can dock a tanker rocket

     

    As long as the Titan has a TWR of 1.2 or higher, it can make orbit.

    literally when the ET is ditched, it’s still 1/3 full of fuel

    Unlimited Aerospace Presents...

    The KBS-45 Poseidon

    Figures:

    Mass: 35.87t

    Cost: 66,508,000

    Parts: 134

    Passengers: 72

    Size: 16.91m x 5.41m x 19.74m

    Cruising Altitude: Anywhere lower than 10km

    Fuel Consumption: 0.18 Kal/sec

    Category: Seaplane/Small Regional Jet

    Details:

    After running through The Janitors a fully qualified engineer's notebook, we found an idea to make trans-kerbanic turboprops much safer, "why not attach floats to a Turboprop" was written in bold letters. So we got our designers got to work making this idea a reality, and out of that came the KBS-45. Nicknamed the Poseidon after the god of the sea, this jet can function as a seaplane, and as a turboprop.

    The design, based on the Katilina, has a central main hull to support the weight, and to side pontoons to keep it upright. Mounted on the wings are two sets of flaps and slats to increase the lift drastically, allowing a Takeoff speed of 50 m/s and a landing speed of 40 m/s.

    When taking off from water, remember that you'll need to pull it out of the water a little before it can gain enough speed to lift itself out of the water.

    Test pilot review: @Agent Awesome's Unlimited Aerospace KB-90 "Slipstream"

    c0YMyOq.jpg

    Figures as tested:

    • Price: 49,735,000
    • Fuel: 1680 Kallons
    • Cruise altitude: 18,000m
    • Cruise speed: 1200 m/s
    • Fuel burn rate: .55 K/s
    • Cruising range: 3665km

    Test pilot notes:

    Another day, another testing agency running the backlog for KEA. At Skaled Komposites testing laboratories we only employ the finest of Kerbal test pilots and using their extreme flying skills we try to squeeze each test plane to the max. We put it through it's paces and then see what's needed to get it to perform adversely and see what's needed to stabilize the plane and not crash it. Sometimes we get rewarded with a pretty explosion!

    In the case of the KB-90 though, we did not get rewarded with any explosions whatsoever unfortunately, we could have forced it by flying into a building ofcourse, but where's the fun in that? Besides, it would be very unprofessional to crash such a beautiful plane that has been so expertly put together! The KB-90 is every pilots dream to fly. With a take off speed of a mere 60m/s and a stall speed of just 50m/s (which is hard to manage in a plane this fast) it just wants to fly! In order to preserve passenger comfort the pitch, roll and yaw authority have been a limited a bit so as to reduce the G-forces on the passengers and te result is a very comfortable ride.

    According to the supplied brochure the plane flies best at a reasonably slow speed and rather low ceiling altitude for a supersonic jet, but when the engineers saw the positively MASSIVE RAM engine mounted to the back of the fuselage they figured they could squeeze a little extra out of it. In comes Jebediah, coolly smoking his vaper, with his visor down to block out the sun, wearing his leather pilots jacket. Leasurely strolling towards the plane he notices that there is not 1, not 2, but 3 engines on this aircraft! He quickly turns around and returns in his flight suit, vaper safely stored in his locker and ready to go!

    While warned about the loud engine noise on the RAM, Jeb punches it to full throttle on the runway anyway. The engineers, prepared for this where safely hiding in the bunker and wearing ear protection, but we will have to change a couple windows on the SPH and the control tower. After a short run up the plane tilts skyward and Jeb hits the afterburners on the panthers for good measure. Pitching up to 80 degrees, Jeb pretty much takes the plane straight to the skies. At about 11km up the plane starts to decelerate and Jeb turns it forwards into cruise direction. The plane quickly builds up speed and after a while the pathers give in to the raw power of the RAM and shut down on their own. At the recommended cruise altitude and speed a little 5 degree pitch up is required and all three engines are on at about half throttle, this did not satisfy Jeb so he had to try something else.

    The KB-90 can do an impressive 1200m/s at an altitude of 18km at full throttle, we did find that the tail wire starts buzzing a bit, which can be a little unnerving to the passengers in the back, if there were any, because the back end is all fuel for the RAM. So you don't really notice that you're travelling at near warp speed to your destination. The testers in the back mentioned a lack of outdoor views, but lots of fun with the onboard wifi (sharing pictures of Valentina, no doubt). In the front three cabins the opinions ranged from "wow! what a view!" to "THE PLANE IS ON FIRE!!!!" Turns out that isn't the plane so much as the air surrounding it that's on fire, at these speeds the world literally turns pink for those in the front of this craft, so we are seriously considering using it to get to certain honeymoon destinations for those who can't wait to get there.

    The engines are mounted a nice way away from the cabins so there is minimal noise inside the plane, no matter what they say on the ground, we couldn't hear or feel a thing. Unfortunately that also means maintaining 3 engines and a whopping 74 parts. The three engine configuration was advertised as a safety feature, but we found that the plane flies just fine without any throttle and considering the speed and braking capabilities we're certain we could cruise it to any airport in the event of total engine failure. It sure is safe to the  point of overkill almost. But what's worth more than Kerbal life? This plane as it turns out, considering the small amount of seats for the price tag. Even though it's not extremely fuel efficient with a KPPM just above the mid range, the lifetime cost per seat mile is somehow very reasonable, so we believe the financial side of things will balance out over time

    The verdict:

    An impressive, beautiful plane that flies anywhere fast on fumes if it has to and that handles beautifully. To put a cherry on top: it is very hard to crash, takes off and lands at low speeds using a short amount of runway (also without the RAM on full throttle). Skaled Komposites recommends KEA buys at least 10 of these, which they will have to use for a while to earn back the purchase price.

    Thanks for the Review @hoioh

    I’m glad to hear that you like the plane

    In my experience, it’s the best flying craft I’ve ever made

    If you have any feedback I could use to improve it, that’d be lovely.
