Moldaeroservice
Departure: Aeroportul Bălţi-Oraş (LUBAL), Moldova
Arrival: Aeroportul Bălţi-Oraş (LUBAL), Moldova
Date: 30th September 2011 / Seat: Cockpit
-----------------------------------------------------------------------------------------
Cockpit view from Modaeroservice's Mil Mi-2 Hoplite crop duster helicopter registered as ER-23237. The flight took place on September 3rd, 2011 from the small general aviation airfield adjecent to the city of Bălți. The footage shows engine start-up of #2, followed by #1, take-off, cruise and landing. If anyone knows why the engine start-up procuedure calls for two cold starts followed by a warm start, please let me know. Btw, the noise level was absolutely deafening, leaving everyone on-board behind with a tinnitus.

Can't stop looking at that legendary little cabin fan...it has served on so many Russian aircraft/rotorcraft, I wonder they're all made by one manufacturer?
Maybe they made 20k of them in the 50s and just move them into the next platforms when they come along
Bigbrain gulag. One fan. Many decades service. Highly decorated
There are two types of this fan, the first is the DV-3 (ДВ-3 in Russian) and the other is the DV-302T (ДВ-302T in Russian). They both run on 27V DC power.
@@barjan82 Wow! Thank you! Now I just need to find one on the market.
We have a MIL2 on display at the museum at Weston Super Mare. This machine was the first to have twin turbine engines mounted on top of the fuselage, giving much more cabin space compared to older machines with piston engine mounted below the main rotor
i like this old fan !
The fan is so cute🤗
I fly this sometimes in Arma 3, even got the fan. Fun.
sadly arma has a flight model of GTA Vice City xD
@@ZunaZurugi Vice City! perhaps a little harsh a FM like DCS would be a 'nice to have' for heli-sim enthusiasts, for the regular Jo in Arma with less than an hours flight experience, going to crash and burn killing their squad, mission over before it even starts, even the AFM in Arma will require a lot of mastering and a mouse and keyboard won't cut it, Hotas. rudder pedals, Trackir, perhaps even a tri monitor set up to do it properly
Ohh, the legendary fan is squishy!
I was lucky to be passenger back in 1990-91. Can't forget that sound :) Lovely machine.
Magyar?
Hi guys,
Those two failed start-up attempts were caused by damaged external power supply, it didn't provide enough power/energy for engines to ignite. Pilot decided to use on-board batteries after second failed attempt (as he says it @ 0:56), and it has nothing to do with engine temperature.
Well, those were not failed start attempts. Those were done on purpose and called engine 'dry spool' when you spin both engines for ~25seconds after each other without fuel and ignition. You have to do this 'dry spooling' on the Mi-2 (and other Russian helis) if the engines sat a couple days without running. After the dry spool is complete, the pilot flips the switch to dowh position at 0:52 on the engine start panel from 'dry spool' to 'engine start'. When the engine start cycle is started the igniters can be heard.
@@barjan82 Is the term for dry spool "Crank"? On the simulator DCS: Mi-24 the engines have a switch to "Crank" and "Start".
@@fmaj6502 I don't know the DCS simulator, but i think the function is the same. Difference is that in case of the Mi-2 you spool/crank the engine via the starter-generator, in case of the Mi-24 with the TV3 engine you crank/spool the engine with bleed air from the APU.
Those onboard batteries weren't that 'fresh' here. Mi-2 in it's factory config has two 24V Lead Acid/NiCad batteries which on startup first connected parallel to power starter-generator with 24V, then connected in series to apply '48V' to the starter for a faster engine spool. On the start sequence the 24V to 48V parallel-series connection is hardly moticable in the engine sound.
Good helicopter! I want to go for a ride some day!
two cold starts are required to reduce turbine temp. you cant start a turbine if it is already hot. you must run it on the battery with no fuel so the airflow brings the temp down. once the outlet temp is within range you can start it normally. this is why you have the guy in the red jumpsuit. he is providing ground power so the pilot does not have to use his battery to cool the turbine.
Раньше было запрещено открывать дверь пилота в полёте,т.к.были случаи срыва со стопоров и улёта двери в хвостовую балку.
Не в хвостовую балку, а во внешний мир. Не дверь, а сдвижной блистер.
@@K_Tulin Нам не запрещали открывать сдвижную , а до правой сложно дотянуться 😍
@@user-sm4bm8io7b Видимо, бывало всякое - запрещали, не запрещали...
Это на Ми-1 было. У него дверь открывалась против полёта. Мало того, эта дверка иногда вышвыривала пилота из кабины. Пилот приоткрывает дверцу в полёте - дверь распахивается - срабатывает хватательный рефлекс - швырь!
the indicator with the yellow sticker is the fuel gauge the reason its moving so much is because the fuel is moving in the tank from side to side (sloshing)
Привет молдаванам!Там у вас в Кишиневе УТО в аэропорту центральном ещё работает или сдохли?раньше ещеьпри СССР много наших с Украинского управления ГА на Ми -2 переучивалось с Ан-2!эти в отели портновский!эх время было веселое!
Thanks for your comment, now thats what I call real fuel consumption - 100 liters in 20mins... :D
Interesting info, thanks. This means the engines must have operated not too long before we boarded the aircraft. I had no idea the outlets are the critical piece in the engine, thought the turbine discs were more critical. Do you by chance know which indicator in the cockpit shows the engine outlet temperature? And I'd love to find out what the indicator with the yellow sticker is for, it doesn't seem to be very accurate.
@intoxicologist That's not correct on these engines. The temperatures are TIT (Turbine Intake Temperature) and are taken by a ring of thermocouples just before the static vanes at the exit of the combustion chamber. The GTD-350 has a slightly unusual fueling arrangement with a single main injector. The combustion instability gives it a unique bass rumble!
Everytime we start up any of the Mi-2's where i work, i have a huge grin on my face simply listening to the engines spooling up 😀
@@barjan82 I got the same kind of grin when I hear SKN crackling prior to all start-up ops...
Interesting, thanks for clarifying. I was wondering for a while what it indicates. Strange they don't have dividers in the tank to avoid the sloshing which most fixed wing aircraft have.
Because the whole 600-liter cental tank is made of fuel-resistant rubber. It is just inserted into hard case in the center of the cabin.
the oulets are not critical, its just where the temp is taken from. the internal compression blades and ignition chamber parts are critical. these can melt if they get too hot say 800 deg for 5 seconds or 1000 for 1 second
engine outlet temperature is measured on the TOT(turbine outlet temp) ,ITT(internal turbine temp) ,Turb out or EGT (exhaust gas temp)this applies more to reciprocating or piston engines) guage on the instrument panel .If a start is attempted with the TOT too high it can roast the turbine causing very expensive damage. The instrument with the yellow sticker on it quite possibly could be unserviceable with the colour & presence of the sticker indicating as such
It's FUN to imagine it's me flying the helicopter! lol
"Карандаш" на месте. :-):-):-)
Я не понял две прокрутки от сккумуляторов они и так всегда были дохлыми,а аккумуляторы надо беречь.
Это точно! Прокрутил один- запустил, а потом от генератора второй крутишь☝️
the temp gauges are the 2 round one bottom right. they show a very low temp though so i am not sure the pilot is cooling the turbines. maybe the procedure is to run the turbine just in case for a mil mi. in any case the gauges are 0 to 10 . so 6 is actually 600 deg.
It is a fuel gauge. Before take off it showed about 500 liter of kerosene in the main tank, a bit later - 400 liter already ;)
Nyet. Fuel gauge sent for re-education. Much better now
(the gas is swashing from side to side. It didn't actually pull 100 liters. Just old school floating sensor)
130 - 150 liter/hour per each of two engines. GTD-350 is a fuel eater.
Не 150, а 300 литров в час. Машина 50-х годов. Новые - 240 литров.
@1metiz
This is all the footage I have recorded on this flight simply pasted together.
ローターとコックピットの扇風機が連動しているというのは国家機密だ！！！！
Am I the only person here who can say that I spent all my lunch brakes at school inside this helicopter?
It looks like that GPU didn't have enough juice to start up the engines, so he told them to take it away, and started off his own batteries.
Cool
To bad the startup sequence skips twice. do you have the unedited version?
My brain kept telling me the turbine noises were directly related to running that dashboard fan! No! No! I told my brain! But it would not believe me!
well if the Rotor becomes to slow, it will knockout the generators and making the fan stop xD
@maxhovid
Interesting, thanks for clarifying. I can only pick out the captain saying "аккумулятор". Probably time to replace this GPU...
It's to purge the fuel from turbines, or " crank- false start "
you might want watch md 500 start up an limitations to learn about tot temperature. i dont see the yellow sticker you mean
having just read other comments I agree it could be a fuel gauge but maybe the yellow sticker is indicating use it's readings with caution or it's uncalibrated
The yellow sticker is common to all Soviet-era fuel gauges, their WWII aircraft had the same type. It's the same case as how you still see gauges identical to those used in the 1930s-40s in modern Western analogue instrumented aircraft.
e antigo este helicoptero. qual o modelo
The gearbox is really quiet
неужели ещё летаете?
ЗА ВИНОМ ПОЛЕТЕЛ ?
Miért nem egyforma fordulattal üzemel a 2 hajtómű?
Utazón már egyforma, felpörgetésnél nem szinkronizált. Megesik.
Are those AN-2s at 4:29?
yes!
And possibly another Mi-2 to their left.
Чито Гврито))
Mi-2 jak rozkręcał wirnik.....bujało jak pasożydem po pustym sklepie......
