[Update Release] issued 30 November 2024
Hello VSKYLABS SR-71-TB Test-Pilots!
Project update v2.0 was just released! The update is available via the Skunkcrafts autoupdater.
It is highly recommended to download the latest v2.0 base package from your store account.
One of the highlights of v2.0 is the implementation of the physics-based, launchable D-21 Mach-3 drone. The D-21 affects weight, balance and overall drag characteristics of the carrying aircraft, resulting with authentic aircraft handling and performance characteristics.
Interactive/interchangeable SR-71A / M-21 aircraft weight and balance configuration: Version 2.0 introduces a launchable D-21 Mach-3 drone. Originally it was carried and launched from the M-21 which was a variant of the A-12 aircraft. Version v2.0 recognizes the aircraft configuration (if loaded with the D-21 as a 'weapon' or if not), and sets the overall weight and balance characteristics accordingly. If the aircraft is set to carry the D-21, it automatically sets itself to M-21 configuration, which will last until the D-21 is launched. Then, weight and balance configuration will set back to SR-71A mode.
The VSKYLABS SR-71-TB cockpit includes a modified replica of the authentic D-21 startup and launching panel, which was slightly modified to be integrated in the front cockpit (originally it was located in the back seat of the M-21, which was a modified variant of the A-12).
The modified panel in the VSKYLABS SR-71-TB is fully functional, allowing to power the drone, set the fuel pumps, ignite the ram-jet, which spools up to launch-thrust threshold (equipped with a PSIA gauge), going through its FCU tests, then having the 'GO' approval for launch.
Launching the D-21 requires exceeding (or nearly exceeding) the Mach-3 envelope (above Mach 2.7), therefore completing a full climbing profile. Failing to do so will prevent the D-21 from starting up, and the 'NO-GO' light will illuminate.
The release sequence includes an initial pitch-up moment, for clearing the M-21. After the D-21 clears the M-21 vertical stabilizer area, its ram-jet engine spooled up and the initial pitch attitude translated to climb/cruise attitude. This is being simulated in the VSKYLABS D-21.
Here's a short video showing several launches of the VSKYLABS D-21 during early development (additional information can be found in the video details section).
Down also is an introduction video - Lockheed D-21 narrated by Kelly Johnson. A fascinating video showing deeper information regarding the D-21, including the general mission outlines and the launch sequence, with the authentic back-seat panel (08:50 in the video):
VSKYLABS Cockpit-Builders Heaven assignment layer:
Another major upgrade is the implementation of the VSKYLABS Cockpit-Builders Heaven assignment layer, which allows assigning all aircraft switches, knobs, levers, and interactions in a designated, uncluttered section in the X-Plane 12 assignment screen.
To use it for key/button assignments, simply type the name of the aircraft or VSL in the search bar and select your assignment. A sample screenshot is attached below:
