X-88 DART SSTO

=============================================

DART = Dual-mode Aerospace Reusable Transport

Highly flexible & error-tolerant 6-seat SSTO spaceplane for time-sensitive manned mission, VIP shuttle or luxurious space travel to the Mun-circling orbit and beyond without needing to refuel.

-Take off, pull up to 15-20 degrees and climb.
-Should be able to accelerate to >1400m/s before RAPIERS begin to choke.
-Press 2 to switch RAPIERS mode, press 3 to switch on NERV.
-Aim for flight direction or a little bit higher (~20 degrees), raise AP to >80km, shut down engines.
-LOX should be empty or nearly empty by now, which is perfect.
-Aim for flight direction to reduce drag, kiss atmosphere goodbye.
-Use only the NERV to do the orbit insertion burn. (Might require a test-ignition to correct the estimated burn time)
-Should have more than 2100dV @ 85x85km Kerbin orbit. Can take you to quite a few places.
-Not designed to get refueled, but if necessary, only fill up the 4 Mk1 LF tanks to ensure constant CoM. Or fill up all the tanks.
-Press 4 to deploy solar pannels and radiator to eliminate heat for better reentry safety.
-Rentery is quite forgiving, you can choose either a steep descend or longer aerobrake path. The X-88 remains fully controllable during the entire flight thanks to balanced and constant CoM.


-Deorbit and set PE to ~40000m, not ABOVE the landing spot but somewhat FURTHER THAN it.
-Pitch to 45-90 degrees to do the aerobrake. The estimated landing spot comes closer in this progress.
-Pitch to ~30 degrees to "glide" and keep the estimated landing spot constant (more or less).
-Adjust when approaching the the target, use air-breathing RAPIERS if necessary.
-It can land nearly anywhere including in waters. Remember to deploy chute after touchdown. A pin-point landing needs practice and experience however.
