attack helicopter

[Narida]

Making the rotors spin at slightly different speeds (in oposite directions) would make the helicopter turn around, so thats not really a problem
Nice helicopter though^^

[edit] you wouldn't even need a jet at the back to move forwards...[/edit]

Looks pretty good, I'm looking forward to seeing this in-game.

But, how will you turn yourself around? The back just has a jet pointing backwards.

Considering it is a game, I presume the user will simply turn using the mouse.

In all honesty, i'd prefer a cool looking helicopter then one that is flight-worthy in real life.

Looks pretty cool.

I like the jet area place, pretty cool.

But, how will you turn yourself around? The back just has a jet pointing backwards.

i've checked with some people that are planning future concepts on aircraft and naval technologies, they said that by rerouting the exhaust out of the back of the helicopter makes it more stealth towards radar, and that also replaces the need of a rear counter-roadder. (notice the angles in the body) the angles in the body are my attempt at making radar-deflecting angles, i've looked at some sci-fi copters but majority of my ideas came from those things that those people told me, also some of it came from the comanche
(and the jsf's hidden weapon's payload)

stealth is the latest thing in naval and aircraft design

*ps, the roadders will tilt to provide forward motion, backwards motion, and strafing

cool! keep up the good work. Whats the poly/triangle count so far?

[ImSpartacus]

hmm, i agree that the rotors look weak, too thin, a little short to my tastes.

Overall i htink it looks decent, i like the fins at the bac, they give it some character, and those engine lookin things on the sides give it some depth. just fix those rotors and add some detail

..rerouting the exhaust out of the back of the helicopter makes it more stealth towards radar, and that also replaces the need of a rear counter-roadder.

You got the right idea...kind of. When you have a single axis tandem rotor system, the two rotors rotate against each other, thus counter balancing the torque against each other. In a single main rotor system a tail rotor or tail side-deflected thrust is used to counter the torque. Without the counter balance, the fuselage will begin to spin with the rotors the second it leaves the ground. What you are speaking of is combining two rotor wing technologies, which is unrealistic and extremely inefficient. In order to make your model logical, you need to either choose the single axis tandem rotor without a tail-rotor/side thrust, or you need to have a single rotor with the tail rotor side/side thrust system.

It looks like what you have in your model is a single axis tandem rotor with rear exhaust at the end of your tail boom which is completely logical, so don't change that aspect.

Also, a note on single axis tandem rotors...When the aircraft makes a change is yaw (this is usually done by increasing or decreasing the pitch in the tail rotor for a single main rotor system) this is done by reducing the rpms for one of the rotors. The change in rpm's allows the rotor torque to naturally do what it wants to and start to rotate the fuselage hanging below it.

so, mined, what you're saying, realistically is that (whatever you called it) the dual-rotor system won't work with the exhaust going out the tail... it would produce too much torque.

... this roadder is becoming more and more problems as i advance in the project... i'm scrapping the roadder and making a new one (the standard four blade system)

*sry limited knowledge on helicopters; dont know terminology

[mined]

look, I apologize.

I am a little over-zealous when it comes to rotor-wing. It has been a big part of my life and I am extremely knowledgable with first hand experience in this area. When ever I have a chance to pass on some of this knowledge, I pounce.

Please don't scrap your idea. It is looking good. Originally my only advice was to widen the blades. No matter what anyone says, believability greatly enhances the gaming experience. It allows the player to better relate to what is going on.

As far as what I posted concerning the difference in rotor systems, I failed you. I was attempting to help explain differences in systems to help you with your design decisions. What I ended up doing was just further confusing you.

What I was trying to explain, in a nut shell, was this:

If you have a single axis tandem rotor system (which you do in your model) then any counter torque measures on the tail are unnecessary.

If you have a single main rotor system (which you don't) Counter torque measures on the tail are limited to either a tail rotor or an exhaust jet that deflects the thrust perpendicular to the tail boom.

If you choose to outlet your exhaust at the end of the tail boom so that it trails behind the aircraft in a linear fashion, then this has no effect on counter torque.

If you choose to take away one of the main rotors and convert the system to a single main rotor system, then you need to turn your tail exhaust 90 degrees towards the opposite direction of how your main rotor turns.

no, i'm continuing the helicopter, but i'm scrapping the roadder, and creating a better (wider) one, i noticed my mistake and beginning my correction sequence. (i think this time i've got it down for sure)
also, i confess that last time, it only took me like 5 minutes to model the roadders
