Centaurus Alpha XAF-220X Pteranodon IIX

2,798 CenturiVonKikie  1.7 years ago

The Pteranodon IIX (Eight) is an experimental eighth generation exoatmospheric hypermaneuverability testbed made by Centaurus Alpha as a proof of concept for next generation fleet defence fighters, the spacecraft is capable of extreme acceleration and deceleration and is also capable of maneuvering at any speed in any atmospheric medium, or lack thereof.

Her development program began amid rising tensions between the Terran Organization for Planetary Defence and Spaceflight and the Junovian Exploration and Colonial Defence Agency, the TOPDS contracted Centaurus Alpha to develop an exoatmospheric fighter capable of outflying and outmaneuvering almost anything that JECDA currently has and could develop, and on the evening of June 10, 2298 Centaurus Alpha unveiled the Model 210, the first spacecraft of her kind.

Upon seeing how effective and maneuverable the fighter was when compared to Earth's current fighter designs, TOPDS awarded Centaurus Alpha a $74 Billion dollar contract to further develop the design. On December 1st, 2298, Centauri Dynamics, a subsidiary of Centaurus Alpha, finished the development of an inertial stabilizer which would allow the fighter to maintain a stable orientation in space without the use of reaction control thrusters, allowing the RCS to focus solely on maneuvering the fighter and conserving more fuel while also reducing pilot workload.

The spacecraft was designed around the magnetic carriage and docking systems currently equipped on the massive Apophys-Class Fleet Carriers, and as a consequence she has no landing gear. By mid 2300, Centaurus Alpha completed the XAF-220A, Still in an advanced experimental stage, she features an extremely efficient powerplant for both her RCS and main propulsion systems as well as a pair of high yield cannons mounted on her anhedral wings, one of the TOPDS contractors noted how she looks a bit like a Pteranodon, and the name stuck ever since.

The RCS and inertial stabilizer are controlled with VTOL, The higher the bar, the more maneuverable she is. She uses no wing physics of any kind and as a consequence her turn rate vastly outpaces her speed and direction of travel, as such, one must keep in mind that she doesn't fly exactly where she's pointing until a couple of moments pass, especially when flying at low level and at high speeds.

An expert pilot flying this build could theoretically outmaneuver ANYTHING that flies with conventional wings, any first time flyer should start with the VTOL bar raised half way and learn to get used to her, your current understanding of lead and bullet travel will have to change a little when using her weapons, I suggest flying her in gun training to get a feel for her.

As you can see, you can definitely get a feel for her.

I extremely disagree with adding missiles onto this build, as they have aerodynamic properties of their own and will severely affect the design's performance when added, the center of thrust for both the VTOL nozzles and her engines were meticulously aligned and calibrated individually with her center of mass, any slight change to their position will make the ship fly in an unwanted manner.

She has two flight modes, her default flight mode where she flies somewhat like a plane, and Planar flight mode. Planar flight can be toggled by clicking on AG-1 and using yaw to control her turn, she flies like a car in this mode and one must pay attention to that altitude, pitch up a little when flying too low or simply roll against her turn. She also has trim control in planar mode.

Her brakes have a shit ton of power, great for stopping at the last minute or hovering and confusing the heck out of people at seeing a plane do eight mile an hour loops and rolls.

    @CenturiVonKikie Thanks for teaching! I will try out different combinations and setups of those gyro-stabilizers / flywheels in my builds.

    The infinite rotators give rotary motion to the fuselage pieces that act as gyroscopes, they help prevent the aircraft from continuously rotating about any axis the pilot gives input to.

    Simply put, they help the ship slow her turns to a stop in order to reduce pilot workload.

    Great Build! The ship reminded me of the Galaxy on Fire series due to its zero turn radius...

    What are the infinite rotators used for? Stabilization?
