Question Notar

I am just curious as to whether or not the notar helicopters have translating tendancy or not. If not I bet hovering autos are much less of a headache. Just wondering.

Not flown one, but since there is still a sideways force applied to the tailboom to generate the anti-torque I don't see why it would behave significantly different in this respect to a standard TR.

Talking

Having flown a few ,they all vary slightly ,but are not really any different to a normal TR. Except that the pedal travel in the hover is quite large so requires big amounts of input change in any auto below translational, this is why people say they are not as precise I think because of the big pedal movements, but in forward flight the pedals are verty ensitive because of the steerable fin(if YSAS turned off).

If you did a hovering auto in one, at first you would say it was more difficult, after a while its the norm !

thanks for the replies. and by the way I am a student with 20 hours so hovering autos still do give me trouble.

I wouldn't worry about it, I still think that hovering autos were one of the trickiest manuevers required during the practical tests I took, and I have a CFI.....for what that's worth

Question

The NOTAR reacts the same as a normal helicopter. Has all the normal stuff, just being produced by the "coanda" effect and the thruster. I have about 600 hours in them, and the way the pedals react are best described as slow. And you have to correct what you just corrected with them. It is an experiance to fly one in 40 kts of wind.

Question

so would you rather operate a heli that has a traditional tail rotor or fenestron, instead of a notar system? or do the comparative disadvantages of the other systems make up for the advantages? OR is it a non-issue altogether as the immense natural piloting ability of a helicopter pilot allows us to fly anything well... see now I have gone and confused myself. if anyone else understands what I asked feel free to respond. thanks again for all the previous posts.

I perfer a tail rotor over the NOTAR system anyday. I have not flown a fenestron, so I can not say anything about it.
The NOTAR, while it has the same tail authority as the 500E, it reacts slower. The tail takes alot more power to run it (up to about 150 hp more in some situations). It also is affected by the winds in flight more then the 500E.
To give you one example, I had to fly one today. The temp was 30c, altitude was 2,400msl and I was 500lbs under gross. I was maxed out on power inorder to get over a ten foot fence that I was next to. A 500E in the same circumstance would not have been that bad. On some days I end up turning the generator off for the extra power until I get airborne.
And we won't talk about the fun a right stuck pedal is in it.

Barafin, my deepest and most humble apologies. Re your hovering autos, when you are performing them in training, I have found that it helps to focus on a point at least 50 ft. directly in front and use your proferial (sp?) vision to make the small corrections during your descent. Save your rotor inertia for the cushion, and focus on maintaing your spot over the ground with small gentle movements of the cyclic. As long as you are sure of your touchdown height, the rest will be easy! Enjoy your training, it will be demanding but the rewards are more than worth it!!
Cheers!

Thumbs up

Hey thanks for the advice. They are actually much better now with practice(although far from perfect, I dont make my instructor wet his pants) i really appreciate the responses. MD really had me fooled with the NOTAR thing. I would def. take the responsiveness of traditional tail rotors over the apparently slow notar. but then again i notar is a lot less likely to take someones face off. It really is a shame that those things happen so much.

i got my md 600 last week last wed, i cant see why any one has to resort to such dangerous practices to get extra power this notar helicopter is the most powerfuli have ever flown,i have time in md500.enst480.206.350. i do agree that it is very different needing lots lots of pedal but when you get used to it its fab.... something nobody mensioned it uses a awful ammount of fuel regards steve.,.

I think you will find the fuel use is a C47 problem not a notar one, after all they do get 800 horsepower from it !!!!! I know its limited to 530 continuos or 600 for 10 mins, but thats only for the transmissions sake, how is PVs old machine anyway!

And I think Helimark reffered to the 520 Notar not the 600, quite a big difference in horses!!!

Thanks Hoverbox, I did mean the 520N. The 600 is a whole can of worms in its self. Lots of power, very fast, but that is where it ends, IMHO.
