aerobatics?

[renodare]

Dear Members,

I own a Varieze, and I watched a video of Dick Rutan doing some accrobatics, does somebody knows about making those maneuvers, does somebody knows about pilots that does some, etc...

Well anything related to the subject aerobatics and canards would interest me. Fly safe Guys.

[Waiter]

Yes, Acrobatics are posible in an EZ!

 

This subject has been much discussed on this (and other) forums. Take a look at this thread:

Have you seen this page?

 

French aerobatic team official web page (they use varieze and sometimes long ez)

Check these movies as well.

In the end, a Longez and Varieze make a crappy acro airplane. If you mean----can it do acro. If you say it that way, what airplane can't?

 

Just for thought----go fly a Pitts---or some similar airplane designed for acro. Then come back to an EZ----you will then see what I mean.

Acrobatics are NOT possible with any EZ type. There's just not enough room for a running start to launch yourself into the air.

 

Aerobatics on the other hand...

not eze for the pilot but wait until you see some of the Acrobatics that will be performed buy the back seat passengers. Who said you need a running start? how about standing in the back seat you put your hands on the strake and then do a front flip over the strake landing on the ground just in time to catch the canard as the rebound from the back spring is causing the airplane to tip over backwards, while all the time looking very cool and that you planed it that way, while not even loosing his hat. remember as the pilot you are responsible for the passengers all the way to the ground and how they achieve that. even if they are only 10 years old. when asked how he did that he replyed I could do a back flip also, would you like to see me? of course we said no, we had allready seen him do that the week before.

[Drew Swenson]

I stand corrected...

 

And while on the topic of correcting english----need people to correctly use the words "loose" and "lose".

Methinks that aerobatics executed in a LongEze (saw this at Osh 1994) were the most elegant flying that I had seen, since seeing a display by a glider!

 

Yeah, the Pitts does it differently, but that sort of extreme flying does not intrigue me

(message deleted since I found an other thread answering my question)

[ZUCZZ]

What a pity, and here I thought someone said something interesting ...

 

So, I'll pose a question:

 

How does one execute a barrel roll in a canard type plane?

 

What are the actions?

[Waiter]

If able, get someone to show you how to do this: I can show you in two minutes, and have you successfully do it.

 

First, make sure you have plenty of altitude (8-10,000 agl, YES that high), because the first time you try this your going to fall out of the top and scare the living bejibers out of yourself as your pointing toward the ground and quickly building up speed.

 

Second, If you pencil whipped flutter testing during phase one, then do not perform this maneuver, (See item # 1). Go back and perform flutter testing the way its supposed to be done, then replacard the aircraft accordingly.

 

Third, Verify your CG. weight and balance. DO NOT operate past the aft limit.

 

Fourth, In the US, make a note in your log book that you are returning to Phase-One to perform aerobatic evaluations and testing. This makes you legal.

 

OK, Put on your parachute, climb to the test altitude.

 

Do a couple practices first, to about a 45 degree climb.

 

Lightly push the nose over to build up to 160 kts. Pull back and hold the stick with about 2 g's. When the aircraft is 45 degrees, push the nose back to straight and level, you'll probably go ZERO gs for a few seconds. You should have about 140 kts at this point.

 

When your comfortable with this, continue to the actual roll.

 

 

As you reach 45 degrees, This will require coordinated controls:

 

Start easing up on the aft stick, quickly (but gentle) apply full left stick and start putting in full left rudder, at the same time continue pushing the nose down as the aircraft goes inverted.

 

If coordinated correctly, the plane will be straight and level, while inverted, and you'll be pushing the stick forward as you continue the roll.

 

 

NOTE - If you have inverted oil and fuel systems, this is a good place to fly inverted, with an indicated airspeed of about 130 kts, and a deck angle about -25 degrees, holding strong nose down on the stick.

 

As the aircraft continues to roll start easing the stick back to the straight and level position.

 

After a little practice, you should be at the exact same altitude and heading that you started from.

Thanks for talking me thru this, I can now form a mental picture.

 

Since I'm still in the test phase, I'll stay there & get my friend with the LongEze to demonstrate this a few times ... he does it every single time he takes to the air.

:ROTFLMAO:Thanks Waiter, a Velo friend of mine described trying a loop in exactly these terms... it worked out, so it's quite funny... now... it took a few weeks to get to funny, though. Be careful out there, folks.

The problem most people have is not enough airspeed to maintain level flight while inverted. (hence falling out at the top of the roll). If you don't have enough airspeed, the roll quickly turns into a downward spiral.

 

I've found I can maintain level inverted flight, but I need at least 130 kts and full nose down (forward) stick.

 

I'll take a inclinameter with me next time I do this, but I'm guessing the deck angle is probably around -20 degrees to hold level flight.

There was this feller doing aerobatics in a Long/VariEze at Osh many years ago (1994). he did loops too.

 

IIRC, Sport Aviation had an article on the man, they stated that the plane was stock standard ...

 

So what would have been his entry speed for that gracefull loop?

[Waiter]

Almost identical to the roll,

 

 

Instead of starting with a 2 g pullup, you need to be more aggressive, with an initial 3 g pullup. Then instead of putting in aileron and rudder, keep pulling the stick back.

 

Again - READ my first post items 1 - 4.

But these maneuvers, are they limited to certain canards? I read in another thread that the Long-EZ could perform them, but the Cozy could not because of the wider fuselage?

[ZUCZZ]

Waiter, thanks for the pointer.

I've never flown a Covy IV, but I see no reason why not. Entry speeds may be different, but it should be do-able.
