DS-7 'Ghost'

DS-7 'Ghost' is a reusable spaceplane OTV (Orbital Transfer Vehicle) made to fit within a 5m diameter fairing.

The base design is 9.35m long, 4.95m wide, and 2.25m in depth. It weighs 6.89t and a Delta-V of 1.98km/s using 2.78t of monopropellant.

The fuselage is 1.5m in diameter, and has a 3.1m long payload bay. To generate power it has 2 fuel cells (also used for disipation of excess fuel for entry) and static panels along the floor of the payload bay.

It has an ACS/RCS thruster system for orbital manouvers such as docking, and a seperate system for use during entry and aerobraking. Inaddition it also has control surfaces on the wings and a gyroscope for additional control.

It has an optional 5.6t, 3m diameter service module that provides an extra 716m/s of Delta-V using the same monopropellant fuel and thruster. With the service module attached, it weighs ~12.5t and is increased to 11.2m in length. In addition to the extra fuel, it also provides an extra 19.46kW of power with a deployable solar array.

The vehicle also comes with a scalable docking module and a solar array module that provides an extra 26kW of power. Both of these modules are intended to be stored within the bay in place of or in tandem with payloads.

(During entry, you need to reduce the fuel level to 10-15% for balance, and it will gradually decrease as you descend due to thruster use. As you get below certain speeds and altitudes, you will need to disable the thrusters and command disc and rely solely on manual flight with the control surfaces. Aerobraking and entry should initially be done facing radial out, before gradually tilting into horizontal flight once slow enough to allow a glide landing.)

Extra Information:
The spacecraft has been being worked on for over a year (well before the release of the DS-6 ATV) and at one point was intended to have a robotic arm, but I couldn't figure it out. I likely will still work on the arm over time, but I wanted to release the actual design now that it's ready.

The rest of the DS series that I plan to release includes converted airliners, dedicated cargo aircraft, an update to DS-5, an RQ-4 style drone, helicoptors and tiltrotors, a light utility aircraft, 3 multi-role fighters from a 4.5th to a 6th generation design, light patrol and trainer aircraft, bombers, a CAS aircraft, fighter and strike drones, and eventually some ground, sea and space concepts.

The commercial concepts being worked on are X-070-SST-NG, X-080/100 narrow-body airliners (same aircraft, different lengths), X-035-ERTP-II, X-125 BWB, an X-015-C replacement, a series of air taxi concepts, a helicopter concept, and many more.
