I don't have my joystick at hand and it is difficult to tune and fly using the keyboard so I'm going to let it sit for a bit. Also worth enabling/disabling some of these effects according to the "flight_physics_level" selector. |

This commit performs a first pass at implementing more realistic helicopter physics particularly at low speeds due to rotor effects: - Improved heading changes when pitch/banking, ported from @metiscus fork - In-Ground-Effect (IGE): thrust boost when close to ground - Transverse Flow Effect: roll,bank effects between 5-25 knots - ETL: thrust penalty below 24knots, roll-bank effects - Torque: heading changes at lower speeds + higher collective The effects make landings more realistic and challenging.

I had added a rotor_diameter model option, but the models already define rotors and their diameters using "rotor_new". The only combination that serves to differentiate and count main rotors is that they either have "follow controls" set or they are "tiltable" (ospray). When more than 1 main rotor is identified (v22, ka-25), then torque and Transverse Flow rotor effects are compensated and disabled.

Tested and I'm ok with what is achieved. Makes hovering on landing more demanding and fun. Merging... |
