Description

A V/STOL tiltjet aircraft called AC-974 Tunguska Gunship aka The Flying Turkey.

Characteristics:
  • tilt angle can be changed progressively, anywhere in between 0º - 90º, without switching the vessels and with almost zero counter-torque effect.
  • the controls for engine servo and surfaces remain on the main vessel throughout flight. Only throttling and swapping wet/dry requires switching.
  • for autonomy it’s always preferable to add or remove LF barrels in the engine shaft, and not in the engines nacelles themselves.
  • for RCS thrusters to work, just threw some LF&oxidizer in the wings
  • vertical landings are a bit challenging, requiring switching back and forth between vessels to find the optimal thrust for descending, and cutting the engines off just before touching down.
  • the design is nowhere near performance oriented, but rather a display of shapes; there are many props and useless parts which hinder the flight performance and efficiency, but still, it’s very fun to fly.

Details

  • Type: SPH
  • Class: aircraft
  • Part Count: 309
  • Pure Stock
  • Built in the SPH in KSP version 1.6.1.

!!! Notes/Updates:

With this one, I continued to exploit the the Cargo/Airbrakes bug for engine stepping actuation. On rare occasions the servo refuses to work or it simply goes boom in the sky. Still work in progress to address these situations or better ask Kraken about this.

Updates:

1.0 - I’ve made some tweaks to the servo, it seems now it’s much less prone to malfunctions. Please let me know if you are still experiencing problems or other issues.

Controls:

After activating SAS and decoupling via [Space], the resulting parts can operated with []:

1. The aircraft body:
  • main control surfaces: conventional keys
  • extend/retract gear & brake: standard keys
  • the Slats [AG9]
  • switch between different pods: [AG3] [AG4] - usefull in hovering mode
  • engine actuation is done via two Action Groups keys:

    • [AG1], double press, to direct thrust backwards. The actuation extent depends on the delay between key strokes, eventually, for full/max engine excursion, press the corresponding AG once >> wait for full excursion >> press the AG again to close the sequence.
    • [AG2], double press, to direct thrust downwards. The actuation extent depends on the delay between key strokes, eventually, for full/max engine excursion, press the corresponding AG once >> wait for full excursion >> press the AG again to close the sequence.
2. The engines assembly:
  • engine throttling, standard keys
  • switch engine’s wet/dry mode: [AG5]
  • toggle gimbal: [AG6]
