Maverick24 Posted August 6, 2017 Share Posted August 6, 2017 Hello all, I would like to ask if anybody has problems I have during startup: - ignition time - push zapusk button and there is 4-5 seconds hang till revolutions start rising - "Autostart Acitve" indicator - according to flight manual it should be off till 30 seconds. In my case it´s about 40 - engine temeprature during startup - it reaches almost 850°. According to flight manual it should be 780° (in last Mi-17 I saw (my father) it was 650 - 700) - engine accelerations - according to flight manual it should be 3-6 seconds. In simulator is this value almost 10 seconds, with noticed hang at half of way to top and from there is 5-7 % difference between engines till reaching the top. - reaching idle after startup - it should be 60 seconds according to flight manual. In simulator is 70 - 80 seconds. Except ignition and acceleration is everything reason for interrupt startup. I wasnt fly Mi-8 for about 4 months, now I let DSC update what it wants and suddenly theese problems appear. I never met theese problems before. Tested at Sochi = almost sea level, outside temperature 16°, Summer season, "engine conditions" is 90%. Could someone confirm my "research" ?:) Thank you Jiri Link to comment Share on other sites More sharing options...
lmp Posted August 6, 2017 Share Posted August 6, 2017 Here's my go. Tested in Kobuleti (28m ASL) in default weather (20 deg. C). I turned on the power and the systems, let the APU spool up, waited 1 minute, as told by the manual, and started the engines. I measured the time with the stop watch in my cell phone from the moment I started pressing the START button. - Revolutions dial started going up after 5 seconds. - AUTO IGNITION ON went out together with STARTER ON at 60% RPM - 50 seconds - Temps peaked at ~680 degrees - Idle after 55 seconds Only the AUTO IGNITION ON light behavior was inconsistent with the manual.

Maverick24 Posted August 10, 2017 Author Share Posted August 10, 2017 I´ve done some another testing with my father next to me (test pilot Mi-8 and Mi-24), with the real checklist and real flight manual. I apologize for little miscounting. Only thing I can confirm right now is very slow increasing RPM of main rotor till around 40%. Because is too slowly, "Auto ignition ON" goes off very very late, real pilots would interupt startup long time before. This should not take a long time with testing at Belsimtek itself to see my point, so I hope they will fix this, or write some explanation.

msalama Posted August 25, 2017 Share Posted August 25, 2017 Looks OK on my end at least. 25 seconds each engine on a cold winter morning in Nevada, which is well within specs AFAIK. The DCS Mi-8MTV2. The best aviational BBW experience you could ever dream of. Link to comment Share on other sites More sharing options...
