That annoying La5 canopy.

[Gump]

This thing drives me nuts!

.

can i get a mechanic to install a screen door latch to keep the thing open?! did they really slide shut when pointing the nose down? of course it happens at the most critical times, like in a dogfight.

.

if there's a lock, im missing it. plz inform me (i know its not ctl+e).

Not? I always thought crt+e really is a lasting solution to canopy locking troubles?

[taffy2jeffmorgan]

I know there is an effect now added to the sim, where the cockpit hood can not be closed after some aircraft have built speed, but i did not know that they can also fly open ? the German/Italian a/c cockpit are held shut by a latch.

they are all locked when closed. when you open them however they may slide back and forth when flying too steep manouvers.

[SYN_Mike77]

Pretty sure all the sliding canopies slide shut now, I know the one on the Yak does!

[216th_Peterla]

And both IL2'S also

[Dutchvdm]

And you can't close them if you are going to fast.

 

PS: Does flying with open canopy give a speed penalty?

I believe it does, but no tests, just a feeling.

[Feathered_IV]

If it cannot be locked, does it slide open in a climb?

[Lusekofte]

It might be historical look how easy he close this canopy

 

[KoN_]

Slide Canopy will close at slow speeds , and open at slow speeds , tested in 190 . And there is a slight speed penalty if open .

Fairly sure they are 'locked shut' evidenced in the Mig 3 vid (latch), some very early cockpits had a habit of jamming shut, leading some pilots to remove them completely (Yak-1 I believe)

The MiG-3 locked up at high speeds and pilots had it removed in 55 IAP after June 1941 because pilot Lukashevich entered a spin and couldn't bail because the cockpit locked. He recovered in the end, but later on he was killed when testing his MiG-3 after receiving it from the rear repair workshop. The workshop's staff ignored his request and refit the hood, and when the aircraft suffered an in-flight failure the cockpit jammed and there died an experienced pilot.

some of these canopies block a pilot's view more than others. the la5 has that horizontal bar very near (or at) the pilot's eye level, and it seems to always be in the way of vital visual airspace. sure, you can go around constantly rocking the wings to see 'around' it, but a dogfight or gnd attack often requires NOT losing sight, even for a moment, of 'things'.

.

i would think it would be even more important if your (real) life depended on it. that's why i doubt that a real pilot would tolerate it if he didnt have to. and i doubt it would be very hard to install some kind of mech stop/latch to keep it open (field mod). this sliding behavior would be glaringly obvious in any test flight - surely it wouldnt be tolerated?

anyways, to cheifwhitehorse, that silly hat i have to wear for trackIR already messes my hair up. ;>/

think aboiut the wonderful scenario where your injured plane is heading for the ground, but you cant bail because the canopy keeps trying to 'auto-close', pinching you in, snagging your chute and buckles. procedure: remain calm and do not use profanity.

Think about all the guys who didn't have a "Refly Mission" button and died because of a jammed canopy or some other reason that prevented them from bailing out.

well, im glad the dev's cant add a bad rivet in my chair, not supposing they'd 'want' to or anything - just saying.

In this video you can see him unlock the open canopy before he slides the canopy shut.  After the canopy is shut (and his hand is out of the way) you can see the cable attached to the lever that runs down to the RH track lock mechanism.  The track most likely has notches at each end of full travel that accept a spring loaded locking pin at the end of the cable (or it's a simple friction lock but I seriously doubt that).  I don't know of any flight open-able sliding canopies that don't either lock open and closed or aren't on a drive system (P-51, Fw190) that resists motion on its own..  On a side note like the serious gaps around the canopy.

 

 

At 1:21 - just thought I'd add that.

So, opening the canopy when landing is a waste of time as it will most likely slam shut at touchdown.

[216th_Lucas_From_Hell]

It doesn't, unless you really jack up the landing.

I will check La-5 manual about canopy later when home from work.

 

EDIT:

Well,Im home from work (...well...not directly...a pitstop at the local pub   )

Quick search in pilot instructions for La-5 with M-82 engine (Инструкция летчику по эксплуатации самолета Ла-5 а мотором М-82,НКАП CCCP,ОБОРОНГИЗ 1942)

page 27,Chapter ''Oкончание полета'' = Ending the flight

Original text: '' 4. при подходе к своему аэродрому открыть фонарь кабины и прочно поставить его на замок  '' = when approaching your aerodrome, open the canopy and put it firmly on the lock.

I reckon, in reality, a pilot could stick a bit of cloth in the grooves to keep the cockpit hood in one place when diving. However, I like that gravity works in this sim.

thx a bunch brano. as mentioned by other posters, it only makes sense that any sliding canopy would have locks at both ends.

.

ps...did some more flying tonite (sorting out sound issue) in QM...wow, vertical maneuvers are simply ridiculous - the canopy just slides back and forth as the pitch shifts.

I didn't have much time yesterday to investigate more on the locking mechanism of La-5. It should be somewhere inside technical description of the machine. I'd like to know how that lock worked when canopy was in full open position.

[Jade_Monkey]

Speaking of canopies, can they change the technochat message from "Canopy opens" to Canopy opening or canopy opened?

 

The current "canopy opens" reminds me of the silence of the lambs: "it puts the lotion on the skin"

[Brano]

I just got my hands on La-5FN construction manual

Самолет Ла-5ФН с мотором М-82ФН,описание конструкции,ОБОРОНГИЗ Москва 1944

In fact there are 3 positions where to lock the sliding part of the canopy

1. Canopy fully closed

2. Intermediate/half closed

3. Canopy fully open

System of locking was very simple,based on lever on spring which clamped with 3 small welded locks on the left side cockpit slat. 

I will upload drawing later when home.Cant do that from work due to some smart corporate filter or whatever

About La-5 canopy.

From La-5 frontline trials test report:

-Canopy can not be opened at high speeds. Canopy self-closes during gliding descent because of weak canopy lock in open position.
(Фонарь кабины невозможно открыть на больших скоростях, а на планировании, благодаря неудовлетворительной работе замка, фонарь сам закрывается.)

IL-2 canopy wasn't locked in open position at all.

but isn't a trials test with a plane done to find out where it needs improvement (or if it can be used at all)? wouldn't that notation about the "weak canopy lock" causing a "self closing" event be a trigger for the factory to fix it? or at least it implies that it was an undesirable 'feature' that would cause any pilot to insist his mechanic put a field fix in for. unless, of course, the pilot never had to do any vertical maneuvers, like loops or yo-yos, split-s, BnZ, ...

[Brano]

I suppose La-5 with high gargot shared the same locking system as LaGG-3. I found a description of the lock system in its technical manual. Unfortunately there is no detailed drawing. As Gavrick wrote,maybe because it's malfunction in general it has been changed to the different system in later La-5s with low gargot. It is different system and by design it looks like quick and dirty solution that worked
