The Aeris 4A is a manned stock spaceplane with single-stage-to-orbit capabilities.
During the 0.25 update when the Spaceplane Plus mod was integrated into KSP, Aeris 4A was modified for the new wing and elevon parts.
Craft Description
| “ | The Aeris 4A is a spaceplane capable of reaching orbit, if flown correctly. — Squad |
” |
Features
The Aeris 4A is equipped with two TurboJet Engines for atmospheric flight. The intake air is provided by four Radial Air Intakes and two Adjustable Ramp Intakes. For orbital flight, one LV-T30 Liquid Fuel Engine is provided. The rocket engine will first feed from the tanks mounted to the jet engines.
Four RV-105 RCS Thruster Blocks and four Place-Anywhere 7 Linear RCS Ports are added for orbital control, allowing both rotational and translational movement.
With an Inline Clamp-O-Tron docking port facing upwards, it is possible to dock with other craft.
Action Groups
For faster switching between atmospheric and orbital flight, the Aeris 4A has four action groups predefined:
- Activate turbojet engines
- Activate liquid fuel engine
- Shutdown jet engines, toggle intakes
- Open docking port
Its engines are supposed to be controlled through action groups, not through staging.
Possible improvements
Whilst the supplied plane does perform ok, there is some scope for tweaking and/or improving the design, with some quick and easy changes. These are just some basic ideas and things to try out:
- Change the LV-T30 Liquid Fuel Engine to the Toroidal Aerospike Rocket, to reduce the chance of a tail strike on takeoff and landing, and arguably improve aesthetics. The aerospike engine is also more fuel-efficient, but has only 81% of the thrust (still sufficient to achieve a 100 km circular orbit from a 20 km transition from jets). This change had been applied to the stock craft in 1.2.0.
- Change action groups 2 & 3 to toggle the engines, instead of just activating them. It is also possible to change the first action group, but this is only required for starting the engines on the runway.
- Remove the Inline Advanced Stabilizer, as it's really not necessary with the changed SAS system. The cockpit now provides both sufficient reaction wheel torque and SAS. Atmospheric handling is arguably improved with less torque.
- Move the nose wheel backwards, under the main body (e.g. under the docking port body section), to eliminate the approximately 2° nose down attitude when sitting on its wheels. This also helps to reduce body flex when sitting on the wheels. It is also possible to rotate the wheel so it's folds forward like the wheels mounted at the rear.
- Add struts between the cockpit and fuel tank or wings, to reduce flexing around the RCS tank and docking port (now obselete as of 0.23.5, as node connections have been revamped).
- Add batteries(if not there already, depending on version) and solar panels, for extended duration orbiting.
- Change the AV-R8 Winglets to Advanced Canards on the nose, and Standard Canard on the tail, for improved handling.
- Add a ladder onto the cockpit.
- Unlock steering on the front wheel using the right-click tweakables menu.
After some of those improvements the centers of mass and lift may change which should be compensated by adjusting the wings forwards or backwards.
