The canopy thingie

[hitman]

ok to my knowledge, the canopy glass doesnt "shatter", the whole darn thing just gets blown off once the det-cord pulverizes the lock.

 

 

Still intact isnt it? Seen TOPGUN? I am sure you have, their canopy blows right off doesnt it?

 

Yep. Lets watch that TOMCAT go down short of the runway like most of them have.

[hitman]

Post a picture of the canopy in question and I'll tell you if it's det cord or not. The Marine Corps Harrier has det cord in the canopy.

 

Ive always wondered what that was. I was even debating asking this yesterday...

Holy crap hitman your a like another Jessica Simpson when it comes to F-14. That footage was being filmed on the first "TEST" flight of the F-14, December 30, 1970, the real first takeoff was on the 21st. Here are some articles on the tomcat and of what happened that day. http://www.csd.uwo.ca/~pettypi/elevon/baugher_us/f014.html

For once, PLEASE LOOK SOMETHING UP BEFORE YOU POST ANOTHER STUPID REMARK/THING that can really get you back

 

Disaster struck on the second test flight on December 30. During this flight, the aircraft suffered a primary hydraulic system failure and began to trail smoke. Millar and Smythe immediately turned the plane back to the Calverton field, and used the emergency nitrogen bottle to blow down the landing gear in preparation for an emergency landing. However, just before reaching the end of the runway, the secondary hydraulic system also failed and both crewmen were forced to eject. Both Millar and Smythe survived with only minor injuries, but the aircraft was destroyed.

Some people have tried to answer this post and and some, like me, have gone off on wild tangents. Try not to get frustrated.

 

Back on track it looks like hes talking about the F-14 cockpit. I found another picture of the lines hes asking about. I do not know if these are detcords or not. Judging from their position directly over the head of the pilot and rio, I would say that they are. However, while searching the web for photos, I notcied that these line may or may not have been removed from the later versions of the Tomcat.

 

Hope this helps

And I think its an accurate description of how well the Tomcat has served. :)

 

"Crashed and burned, eh Mav?"

[hitman]

If you wanna see it up close, there are some great shots in the Swartzenegger movie True Lies.

 

Ive been in the cockpit of a few harriers at airshows, notwithstanding a few governator movies.

hitman just shut up and go stare down a dictionary of Naval aircraft because you obviously have NO knowledge what so ever of the USN. Personally if you said that to me, you won't really be talking right now because it just makes me mad how uneducated you really are!

Corsair your correct. I have no idea about anything in the USN. I only served with the Department of the Navy...the Mens department.

 

Your rhetoric about all this F-14 pwnz all xcept 1337 -22 raptors is a big load of BS and Ill admit its getting quite old and embarrassing for you. The F-14 is plain and pure garbage compared to the -18E/F. Get over it. I suggest HIGHLY that you remove your head from your posterior in a neat and orderly manner and expedite that order as well.

ooooooow the Department? what did you do, file papers? cause you seriously have no clue what your talking about!

 

And one question, how old are you....really???

Ok kid. The Men's department of the Navy would be the USMC. Take it up with gramps, and if you even HAD a clue about what my age was, you should be looking at my profile and not asking these dumb questions.

 

My age-between 12 (most of the times) to 45 (when kids piss me off).

 

Your age-between 11 (all the time) and 12 (on a good day).

 

If you want to keep this personal, Ill assume that you know how to pm people...but you know what they say about assuming things.

File papers.... doubt that.... Hitman was one of the few and the proud... but if you tried to research on here instead of troll you would learn a thing or two..

 

BTW have you been in the service of your country yet?

 

And one question, how old are you....really???

 

I would direct this to you, because ....... no offence to our fine valued forum members from the USA you are coming across as a typical spoilt juvenile "yank".

[hitman]

Whats long, hard, and full of seamen? Wait...that one is old. Ill google one up really fast.

[hitman]

Why did the Navy change from using bar soap to using powder soap?

 

 

cuz it takes longer to pick up!!

 

why does the navy blow sands before entering port? -- so we can crap on the coast guard.....................a coast guard mother told her son she was proud of him and told him that she regreated that he never met his father but that he was a sailor too...

"really mom, what was his name?" he asked, "I’m not sure" her in response, "what mom, you don’t know who you slept with?"

"of course I do baby like every good coast guard mother, I slept with the navy’s pacific fleet".................. old sailors say " it is better to know your father was in the navy and not know his name, than know your father’s name and know he was in the coast guard.

My haircut is always in a high and tight...and a bad hair day is when it gets above a half inch. :D

Great you guys, you are just killing the thread and making the Mods close/delete it. :cry:

[spugnut]

The GR.1 was fitted with a Martin Baker Mark 9 rocket-boosted zero-zero (zero speed, zero altitude) ejection seat. Instead of blasting off the canopy, the GR.1 had a string of "miniature detonating cord (MDC)" ribboned around the top of the canopy. Before ejecting, the detcord would blast the top of the canopy into fragments, and the pilot would eject through the hole. Although this is a fairly common measure now, the Harrier was one of the first aircraft to incorporate the scheme because, in hovering mode, blasting off the canopy would have thrown it straight up, and the ejecting pilot couldn't have missed it.

 

Ref: http://www.vectorsite.net/avav8_2.html

 

So, I would guess the easiest way to tell if an aircraft uses canopy seperation or detcord fracturing is to check if it has zero-zero ejection capability.

Great you guys, you are just killing the thread and making the Mods close/delete it. :cry:

Yeah some of these members should really be taking their petty arguments to the PM and bitch slap each other there.

 

Ok let me spell it out for you Black Hawk.

 

Since you have been quite general in your question "canopies of some aircraft" the answers you have received in return are also general. Then after a bunch of answers and some fun ones (because we have a sense of humor here) you then become specific with a image of a F-14........so is it the F-14 or all military jets ??

 

Here are some general answers rounded up to make it easier for you to read:

1. Fast jets to my knowledge do not have de-mist/frost cords they have heat blowers.
   
2. Fast jets do have det cords to shatter the plexi-glass canopy.

Then on to your attitude in return for the time people have taken out of their lives to help you with your quest for information.

First, I get irritated when people put my nick the wrong way, it is Black_Hawk

Second, why do you guys always have to mock everyone about the things they want to know?

If it were up to me, I'd ban anyone who would violate forum rules and policies without the WARN. And the moment people get through your next alias you'd get banned again. But it is not up to me and I cannot do anything about it.

 

So, to end the discussion, none of you actually know what the cord is used for in general... You could have stated that at the begining of thread instead of spamming. Sometimes the forums were places where you could actually find something out. Now it's just about making fun of ignorant ones.

You wonder why people "mock" your question when its as open ended as a episode of Lost? After 5 pages of answers i would have made a conclusion that unless your asking about a specific canopy you not going to get a specific answer!

 

I find it quite shocking that you hold a moderators position over at lockonfiles.com with this sort of attitude, glad i dont post their.

[Black_Hawk]

Well the people over there (at the LOF) take questions seriously, and people answer them seriously. I see no reason to be shocked for my position over there. I earned it with my behaviour (so no bitchin around).

 

I just thought it was a general thing so I figured that the answer would be general too.

And I'm not pi**ed about people making fun of themselves whenever a thread reaches page 2 or 3; I'm actually sad about that because in 90% of the cases they cross the line and the thread dissapears. Maybe someoue could have found the info on page 1 helpful.

 

At least I pulled something useful from 5 pages of this thread, thanks to everyone that actually tried to explain it to me.

1. Fast jets to my knowledge do not have de-mist/frost cords they have heat blowers.

True. The canopy defrosters are ducts that direct heat from the engine bleed air to the inner surfaces of the canopy. Wire-type defrosters are composed of such small wires that the only hint of them you can see in an installation like that are actually the temperature sensor wires. The actual heater wires aren't really visible to the unaided eye.

 

2. Fast jets do have det cords to shatter the plexi-glass canopy.

 

Not always, but many do. ;) The det cord which allows the pilot of a Harrier to eject through the glass is there for essentially the same reason A-6 crews also get shot through the glass. Both aircraft have sliding canopies

which, due to lack of sufficient airflow under the canopy at times, could possibly get stuck in their open position. If that were to happen, the aircrew would be shot right into the canopy frame. Therefore, the aircrew of both aircraft are shot directly through the glass. Slower aircraft, like the A-10, usually shoot the pilot through the glass as well, due to the lower speeds. This is the reason for the "horns" on the top-front of the headrest of the A-10 ACES II seat. Those are the canopy breakers. The Mk 16L in the ATG Javelin also has canopy breakers, as its seat will also be shot right through the plexiglass.
