    Advanced Helicopter FDM Feedback

    Boy does that explain a lot. I have been wondering why that is for a year!

    This is further proof that the limit droop improvement is not working properly in the flight model.

    Found this in DCS huey POH. It really feels like this is missed which is odd considering it's suppose to be 2030 something. "Without this characteristic instability would develop as engine output is increased resulting in N1 speed overshooting or hunting the value necessary to satisfy the new power condition." Damn n1 won't keep up! Not only that but it creates WAY too much yaw as RPM constantly fights to keep up. 2.4.5. Droop Compensator A droop compensator (#1 in Figure 2.8) maintains engine rpm (N2) as power demand is increased by the pilot. The compensator is a direct mechanical linkage between the collective stick and the speed selector lever on the N2 governor. No crew controls are provided or required. The compensator will hold N2 rpm to 6600 rpm when properly rigged. Droop is defined as the speed change in engine rpm (N2) as power is increased from a no-load condition. It is an inherent characteristic designed into the governor system. Without this characteristic instability would develop as engine output is increased resulting in N1 speed overshooting or hunting the value necessary to satisfy the new power condition.

    I can tell you that it is unrealistic. The affect is called Gyroscopic Precession which is when a force is applied (cyclic input) the reaction occurs 90 degrees later. So think about how long it takes for a rotor blade to cover 90 degrees and that is the amount of lag you should feel when making cyclic inputs. You all can test this by going from a hover into forward flight. Your helicopter if it's NATO should roll to the right (or to the left if it's a hellcat. This is called Transverse Flow Effect - as the helicopter accelerates into forward flight induced flow (downforce) drops to near 0 at the forward rotor disc area. This increases the angle of attack at the front rotor disc area causing the forward blade to flap up, and reduces the angle of attack at the aft rotor disc area causing the rotor blade to flap down. Because the rotor blade acts like a gyro (gyroscopic precession) maximum displacement occurs 90 degrees later in the direction of rotation. The result is a right roll as you accelerate past around 20 kts or right before ETL (effective translational lift).

    It's definitely there with Thrustmaster warthog hotas. It has to go, I don't understand why it was there in the 1st place.

    Gatordev settling with power can be practiced at altitude, the instructors put you in it and you get yourself out of it. On that note there is a new way to get out of it beside 1) lowering collective 2) forward cyclic 3) pull collective. The new way they teach it is 1) aggressive right cyclic 2) pull collective 3) LEFT pedal (or the reverse). You lose less than half the altitude, something that is precious when VRS happens on accident on approach to landing.

    I can tell you that in Robinson R-22's and R-44's, which is all I have every flown, both the cyclic and collective are VERY responsive. Most of the time if someone is having issues its because the controls are too responsive and they over correct.

    VRS and settling with power are the same thing. Trust me I have been in it several time in real life and it's on both FAA exams. ---------- Post added at 08:43 AM ---------- Previous post was at 07:57 AM ---------- This guys information is correct.

    Arma 3 Helicopters DLC Discussion (dev branch)

    Henry Rollins replied to FredAirland's topic in ARMA 3 - GENERAL

    I will give You 3 reasons: 1. Ever had an engine failure? Engine tach goes to 0 you immediately autorotate. 2. Ever descended so fast you overspeed the rotor? When the red light comes on it's already too late. 3. Ever takin off with a heavy load in a little bird. Engine rpm lowers to the point of stalling then everyone dies. On the 3rd reason BH will you please add a low rpm warning horn along with the light??

    I don't know about you guys but I could really use an engine and rotor rpm gauge.

    Henry Rollins replied to aluc4rd's topic in ARMA 3 - DEVELOPMENT BRANCH

    If you ever played TOH when you use max power and your torque indicator light turned red for too long there was damage done to the gear box which caused the same type of vibrations. I would just guess that you were using a lot of power when you were fully loaded and over torqued the AC.

    Henry Rollins replied to aluc4rd's topic in ARMA 3 - DEVELOPMENT BRANCH

    Until BI implements a throttle separate from raising collective autorotations will not be possible unless you truly have an engine failure ie red in the engine indicator. This is caused by a correlation between raising the collective and turning on the engine. In effect this re-engages the engine drive to the rotor blades disengaging the sprag clutch Which allows us to autorotate. The final affect is a massive drop in rotor rpms causing the blades to stall. IRL we put the throttle into the detent (roll it off completely) to prevent the throttle from correlating to the collective. Or else we would really die just like in Arma 3.

    I hoe they add the TOH startup process which will require the addition of a throttle for helicopters in the controls config section. Same for APU's

    That video is exciting you just experienced retreating blade stall due to passing VNe or velocity never exceed. Nicely done Bohemia!

    Im in Cali. You are using the dev version of the beta. There are less servers using the dev version. I recommend USSOCOM and 175th servers. Non dev version of the beta try Graves, they are well orginized and have a Seattle server, my ping is In the 30's with them.

    Configuring a HOTAS for helo flight

    Henry Rollins replied to coolts's topic in ARMA 3 - GENERAL

    The 50% collective is somewhat realistic. You must pull enough pitch and TOT to get the aircraft off the ground. It will not be at the bottom of the collective and it changes based on weight like weapons loading, fuel etc. Your problem with collective is odd. I have the warthog and am not experiencing the same problem. It sounds more severe than transverse flow effect.

    infantry Anti tank/Anti air to strong?

    Henry Rollins replied to Qosmius's topic in ARMA 3 - BETA DISCUSSION

    If only the RWR's worked in the helicopters we would have a chance. As it is now I find myself staring at the radar. Also there are plenty of MFD's in the choppers that can be used as PIP, I hope they take advantage of them. Finally the helmet mounted displays are far inferior to TOP OWL and other systems in use today. I'd like to see thermals displayed in my visor.

    TOH flight model- if, when, how?

    Henry Rollins replied to samb's topic in ARMA 3 - BETA DISCUSSION

    Settling with power AKA Vortex Ring State is modeled in TOH as well as Auto Rotation.

    I really like where you are going with this. Great potential.

    Helicopter physics impressions - simplified

    Henry Rollins replied to v8_laudi's topic in ARMA 3 - GENERAL

    Love the 5 minutes of inverted hover. :cc: Obviously Bohemia is putting there effort into the real flight model and didn't spend much time with the placeholder. Thank God they are working on the TOH flight model implementation.
