Which is the best chopper design? Why not a single military chopper used NOTAR?
>>64318342Intermesh is best for utility lift. I see K-max doing powerline construction and forestry work on a weekly basis and they're sexo and their pilots have giant balls flying so low in canyons.
Notar is super cool from a simplicity perspective, but its like wearing nothing but crotchless panties in a diverse ghetto, its just begging to get raped. Except from heat seeking missiles instead of blacks, obviously.
>>64318342>Why not a single military chopper used NOTAR?Heavier than a tail rotor setup, reduces lift capacity and rangeSimilar amount of noise reduction can be achieved with a Fenestron
>>64318342No one used notar because MD helicopters is a comically inept company kept (barely) afloat because the world needs littlebirds
>>64318342I was going to say this thing but I didn't realize unitl I saved the pic that it had a little baby tail rotor.

Does the tail rotor help turn the helicopter in addition to cancelling torque?
We'd have more NOTAR birds if the world was less gay.
>>64318342Isn't transverse rotors just tandem rotors but side-by-side?
>>64318342Notar always makes me think of the mafia littlebird from mercenaries
>>64318751turning just means counteracting the torque more or less, depending on which direction you want to turn into
>>64318713This thing
>>64318362this isn't a normal train of thought
>>64318910wrong site for normal, tourist
>>64318353It's a shame Kaman is so dysfunctional.Their shit's really cool.
>>64318342A coaxial tiltwing pushpropYes that's 5 propsYes that's also a tilt rotorNo you can't stop me
>>64318893Haaaaaatttteeeee
>>64318342>Which is the best chopper design?The best design, at least for large helicopters, is most likely the tandem design a la Chinook. No engine power wasted on having to counter torque, each rotor runs efficiently in mostly clean, non-turbulent air. Second best design, for smaller helicopters, is probably the intermeshing system.
>>64318353>>64319025I blame C&C for my love of intermeshing rotors, I NEED a gunship version irl.>>64318842Based.
>>64318893Hasn't this thing been a huge maintenance whore and all around mistake?
>>64318342Tipjet rotor is peak simplicity, no need for a transmission or even electrical power - just pull the cord and let the lawnmower engine spin up the jet engine...https://www.youtube.com/watch?v=dNZcHMgVx6UShame sncaso got baught out by sud oest...
>>64318910Shut up faggot.
>>64318353>>64319025How do they prevent the rotors from banging into each other and crashing the helo
>>64318342Tail Rotor, like God and Igor intended.
>>64320976The rotors are covered in static electricity of the same charge (positive for lift, negative for drop).
>>64320976They've just gotten really really lucky so far.
>>64320976Yeah, the actual answer is that the rotor hubs are literally geared together like the beaters on a hand mixer. It's physically impossible for them to run into each other unless the gearing completely breaks, at which point you're a brick anyway.The downside of Kaman is that it's dangerous to approach from the side, restricting how it can be used. Which is a shame, because they're apparently really maneuverable at low speed/low altitude.
>>64320896I mean like everyone experimented with tip jets and it didn't go anywhere.It's a fun curiosity but that's about it
>>64318893These fucking things fly over my house all the time. They are ugly and IMO should've never been procured. Not to mention it replaced both UH-1 and OH-58, and it still doen't have the capabilities to fully replace either aircraft.It can still be a great aircraft, just a rather lackluster replacement, though there is still time to (mostly) fix that. Not to mention it isn't an domestic American design. >picrel, hopefully the attack/recon version is adopted. The ducted tail-rotor is a nice feature aswell.
>>64318342>Why not a single military chopper used NOTARManufacturer support. MD shilled it then dropped it like a brick so the fleet is near worthless. They convert them now.
>>64320896>Tipjet rotor is peak simplicityBut thats about it, its simplicity is its downfall as it lacks the growth potential of other aircraft, and no "hurr durr just put bigger jets" isn't the way to 'fix' tipjets.
>>64320920>>64318922Hes right tho>but its like wearing nothing but crotchless panties in a diverse ghetto, its just begging to get raped. Except from heat seeking missiles instead of blacks, obviously.No sane man would say something like this. Too much 4chan brainrot I guess, kek.
>>64325142Main problem with most tip jet concepts was that people kept trying to power them with either hot exhaust gases or ramjet engines, which is potentially better but very troublesome from a materials, combustion and noise standpoint. The djinn simply used bleed air from an oversized centrifugal compressor, and worked just fine, even in military roles - and in terms of performance not many helicopters can carry more than it's own empty weight in payload or fly up to an altitude of 8458 meters, especially in the 50's.https://www.youtube.com/watch?v=rENiBIPmih4
>>64325422That looks pretty fucking neat. But more than likely it stayed primarily 'for agricultural purposes' for a reason. I cant imagine it would be very fuel efficient at the least.
>>64325358I'd argue that the specific problem with the xh-17 is that it only used two blades, because it was losing quite a bit of pressure forcing in so much air through the long, thin blades into the indersized tip ejectors. Their next attempt, the XV-9, was considerably more sucessful, even though it ended up not being adopted because the hot gases systems it used ended up making more noise and being a pain to maintain.

>>64325480>comparison to Aeolipilekino of the first degree. The fact it has a little bird-esque cockpit is the icing on the cake.
>>64318342Coleopter is coolest
Small tandems are weird
>>64318757Transverse rotors have lower lift induced drag at speed because they spread the lift over a longer span and don't have one of the rotors lose efficiency from being in the wake of the other, but have a bit more parasitic drag because of the need to reinforce the structure with struts.
>>64318743Freaky looking dude
>>64330256Same regards to the 600
Is there any energy loss due to shaft extensions and joints from the engine?
>>64330283My shaft extension has granted me the might and vigor of a sixteen year old nigger.
>>64318342Rotorless, with ducted fans contained in the fuselage.
>>64318342it depends on usecase
>>64318353Insane how many KMAXs and MD500s are running aroundwith their basket case companies and the resulting parts famine
its a helicopter not a chopper why do you english ppl all say it wrong, if you nerd out over such things at least know the correct words, also obvsly coaxial is best
>>64332563do you pronounce it as helico-pter too?
>>64332563helichopter
>>64332563Stick your head up when getting out of a helo with its rotors running and tell me how it isn't a chopper.
>>64318342Retarded question, I know, but I just realized that I have no fucking idea how helicopters can turn and lean. I see up, down, forwards, back.
>>64332563Heleekaptaar
>>64318362>missiles could be here, he thought>>64320976The pillot and copilote control the revs of the rotor on their side. Since they need to be in perfect synch those choppers are usually only flown by telepathic twins.Don't listen to this fucking troll >>64322115
>>64318842Hmmm since Notar are quiet as heck wouldn't this work as a type of drone?
>>64333845Notar is heavy, probably wouldn't scale well
>>64333135they either lean the whole rotor head, or change the blade pitch between the left and right side of helicopter.
>>64318467>>64318342>Why not a single military chopper used NOTAR?But they did. Special Squirrels used NOTAR'd MD500s for a little bit in the '90s.
>>64325467>doesn't smellwell what does it taste like?
>>64318342Depends on the role. Coaxial is good for compact applications, such as ship-borne roles. They also make good training helicopters (which is why a lot of the cheap RC helicopters are coaxial).Intermeshing is good for utility like: >>64318353said. It is also very stable, but it might be seen as awkward in flight dynamics compared to people new to a type like this.Otherwise, conventional. It is conventional for a reason, and while it does have its problems, it serves its purpose quite well and if generally easier to work on compared to coaxial or intermeshing helicopters.>>64325321>replaced UH-1sI see UH-1s flying over my house multiple times each week. OH-58s (especially the D model) were gone too soon, though. I would not have been as upset, if the ARH-70 replaced it, as it was essentially a super Kiowa, but it was that gay thing instead.Word on the street is that the Thrashers and Grey Wolves are also a maintenance nightmare.
>>64334764Purely on a trial basis and they found it was worse suited for SOAR than the regular H-6 by every measure except being quieter
>>64318342>Why not a single military chopper used NOTAR?fuck off rajesh
>>64318362>>64318922the problem isn't that it's not normal, the problem is that you look at a helicopter and fantasize about getting raped by niggers. you're a disgusting faggot, go die of AIDS
