Advanced Helicopter FDM Feedback
armored_sheep replied to aluc4rd's topic in ARMA 3 - DEVELOPMENT BRANCH
There is no throttle control on Arma helicopters. Collective input does change pitch of the main rotor blades. Each helicopter has different values for main rotor and is performance depends on many factors (actual weight, speed). There is no other way how digital input (such as keybord) can be used for this. Speed of the collective pitch angle change depends on how long does one keeps the key pressed. I recommend users that use keyboard this way, to use the in-game GUI - vertical speed indicator with bar that represents collective setting. -

Blackfoot ability to auto-rotate when engine is off fixed in today´s update. I am looking forward to see your feedback on actual VRS settings. -

There are new values. Hummingbird can enter VRS aprox at 7 m/s, Ghost hawk 12 m/s (descent rates of rotor at 0 horisontal speed) -

AFM simulation is used always only for the human player pilot, so just one helicopter at a time. In MP it is simulated on client that is the pilot. Drawing frame rate should have no effect on simulation except really low frame rates. -

VRS is back in dev branch. Enjoy! -

No. There is no way how to configure changes of rotor axis angle in advanced flight model. -

In today's update you should have all helicopters with VRS set (just except Huron). The weight simulation is repaired. You also get camera shake inside cockpit on VRS entry. -

After some investigation we found the issue - added weight of the helicopter is realy not calculated, so you are flying always with just empty weight. It will be hopefully fixed soon. -

Right. The new RTD libraries / code with VRS changed all helicopters performance. Most noticeable is the vertical speed performance (helicopters inserted flying now do climb instead of steady hover). We are still evaluating the code and it is not sure if VRS will be in the DLC release at the start. It may be postponed to some later patch. -

Why do you think that stress on rotor should reduce always if you pitch up (cyclic imput) during fast descent? RPM on main rotor can rise only when collective pitch is low. IMHO same like with auto-rotation... ---------- Post added at 08:39 ---------- Previous post was at 08:37 ---------- RTD does also simulate the vibrations with VRS, but this feature is not yet fully implemented / visualised in Arma. -

Unfortunately Air_F addon was not updated in dev.branch. I confirm only Mohawk has VRS configured now. -

In todays dev.branch update we will add first implementation of Vortex Ring State. It is now in the code and reads new values from XML config. The first two helicopters configured now are Mohawk and Hummingbird/Pawnee/M-900. -

Actually we have 90% of max available torque as transmission damage threshold and 1/300 damage is applied each second when torque gets over the threshold. According to described formula it means that every helicopter can brake (damage = 1) after approx 5 minutes of shining "yellow" warning light. It can be 4 minutes in case one will be able to keep 100% torque all the time. -

Actually the different values in RTD config (continuous/takeoff/emergency) do not matter in Arma. We did not buy the RTD module that simulates those states. We do damage simulation on our own. This is rather simple. We use only emergency as max (this is the 100% I am talking about). Amount of damage per second (stressDamagePerSec) and maxStress threshold is given in config The damage is than calculated by : stressDamagePerSec * Square(stress / maxStress) When stress is under the threshold, no damage is taken. -

Blackfoot got reduced size of tail stabilizer (less force that keeps you flying straight) ---------- Post added at 09:05 ---------- Previous post was at 09:01 ---------- 120% in real helicopter for you is because 100% probably means guaranteed "safe" torque (maintenance, safety regulations). In game you cannot exceed 100% of available torque defined in RTD config. Simulation does not allow transmission to produce more, so I assume 90% is fair ;) -

armored_sheep replied to aluc4rd's topic in ARMA 3 - DEVELOPMENT BRANCH
More than 90% for at least 5 minutes. The more torque over the threshold the faster it may brake, but not sooner than after 5 minutes. The force that causes rotors disappear is measured for the whole rotor component. -

I hope that artists and coders will have some time to make better visuals of rotor disintegration. -

There are three damage simulations in flight model of rotors. The first is transmission damage due to torque. There is measured threshold and time. Basically if you fly over limit for 5 minutes, the transmission will brake - in game you will see rotor stopped spinning. I use for all western design helicopters this limit at 90% of their available maximum torque. The second simulated damage is actual force on each rotor. RTD calculates force vector on each rotor. I defined in configs a limit of this force in Newtons. If you get over the limit, rotor will instantly brake apart. I would like to use this limit to prevent flight in unrealistic attitude, for example pulling high G or doing erratic moves on high speeds. I spent some time last days trying to find best values for each helicopter. Hopefully in next update you will find them better ;) Last one is collision/hit damage off course. -

armored_sheep replied to aluc4rd's topic in ARMA 3 - DEVELOPMENT BRANCH
I agree that the limits are now not properly set. Technically there is a threshold set for each helicopter where number defines which force will rip the blades off. If you have some reference about maneuvers that should be possible in real life but in game the forces make the rotor disappear, please post them here. tx in advance -

In today's update there will be enabled stress damage on rotors. You find rapid raising of rotor blade angles (quick collective, cyclic moves) and aerobatics at high speeds impossible - because you may loose the rotors without any warning. -

Better report sound or sling loading related issues in different threads or community issue tracker. This thread is dedicated to flight model configuration. ---------- Post added at 09:56 ---------- Previous post was at 08:32 ---------- The camera shaking has nothing to do with simulation. It is only visual effect that designers test based on speed and G loads. -

Yes it is possible. First time we did it on HIND (TKOH DLC) that has horisontal stabilizer tied to collective. Do you have any specific references about angles and speed ranges for those helicopters?---------- Post added at 10:46 ---------- Previous post was at 10:43 ---------- After the flight models settle down, I will revise the collective range (throttle is allways the same on todays helicopters) that angles range is usually defined in XML as "collective * X + Y" to allow best sensitivity for hover at default load but still keep reasonable rate of descent and stable behavior on ground. -

I recommend reading https://community.bistudio.com/wiki/Helicopter_Flight_Model_Config_%28XML%29 to all interested in Advanced Flight Model configuration capabilities (authenticity of simulation). I like to compare in game models with real life references, if you have some, although the scope of Arma is not full fidelity simulation of particular real helicopter models.
