The MBB/Kawasaki BK 117 is a twin-engined medium utility–transport helicopter, originally developed by Messerschmitt-Bölkow-Blohm (MBB), Germany, and Kawasaki, Japan.
Development began 1977, certification had been finally reached 1983.
It was developed from the successful BO 105. So it shares the same scaled up main rotor system and tail rotor. Many variants had been built since then. The now current variant is the BK 117 D-2 by Airbus Helicopters, also known as H145.
Model
The model for FlightGear has been started 2011 by HHS and represents the MBB BK 117 B-2. Due to to real life (Studies, new job, moving, etc….) the development had been delayed a lot.
It features a realistic FDM with very realistic flight handling qualities based on real numbers and plausible flight performance with realistic climb rates and speeds.
The exterior 3D model and UV mapping is currently being remade, since better and more detailed blueprints could be found and used.
The flightdeck in development already has photorealistic controls (stick, collective, pedals, rotor brake), center pedestals and overhead panel. The main panel is in work and will also have photorealistic textures. NAV and COM will be simulated as Becker Avionics, their 3D-models are ready just the systems behind are still missing though.
Dedication
This model is like the EC 135 P2 dedicated to the former user and developer heliflyer, who was an active FlightGear developer and emergency doctor on a rescue helicopter and with that an helicopter enthusiast who passed away some years ago. He provided a large set of HD images with every little detail inside and outside of the BK 117 which is base of the textures used for the flightdeck. More important, he delivered a lot of important information for systems simulation and flight dynamics.
Other models
Other models found on FGUK or FGMembers are just derivatives from this model described here. They are not endorsed and supported by its original main author HHS.
Help needed and not needed
Instead of having many unfinished versions floating around, help the author instead to get this helicopter ready to fly and work with a developer with many years experience in developing for FlightGear. The model will be available on FGAddon and released under GNU GPL V2.
Help needed
- Systems like electrical, avionics, ...
- Liveries (paintkit will be provided)
- Testing and debugging
Help NOT needed
- 3D generally
- Interior textures for cabin, flightdeck, etc….)
- FDM
- Engine simulations (engine start up, ...)
Contributing
Interested to help?
Applications to HHS until end of November 2016, start will December until February, main work will be done on the weekends and evenings central European time, development place will be GitLab or GitHub (probably the later one).
