exactly the way like the russians like to design it... big, chunky, and armed to the teeth
-
woah...nice
-
woah, i must say it does looks like the apache............still bear some resembelence to the hind.........if this IS the hind, then forgive me as i am not good with planes and choppers
-
wow... i bet this russian helo pack a punch but it's really big and bulky....
btw i got a question to ask:
Most helo got 2 rotor, 1 main tandem rotor and a tail rotor, is it that the main rotor keeps n makes the helo up n stay in the air? Then how the helo moves forward, sidewards n backwards? -

wow.. look power... haha i bet its damn cheap too compare to the USA one.

Well for most modern choppers, they are equipped with a jet engine to propell it forward. Change of direction is done by changing the pitch and angle of the main rotor and by rotating the heli along the normal using the tail rotor.Originally posted by Arena:wow... i bet this russian helo pack a punch but it's really big and bulky....

For choppers not equipped with the jet engines, the main rotor is tilted at a forward angle. Hence for some choppers you notice that its angle of attack is pointed down when it is moving forward. -
uh centurion, i'll have to correct you on this one
the heli's main rotor has two kinds of control, the collective, and the cyclic. the collective alters the angle of attack(the bite into the air) of all blades. more pitch, more lift. the cyclic control alters the pitch of the individual blade. for example, for the heli to pitch down, the blade travelling over the tail has more pitch and lift, while the one over the nose has less pitch and lift. thus, with this moment, the heli will pitch down. the tail rotor acts as an anti-torque system, or else the heli's body would spin uncontrollably. excess tail rotor thrust is used as a rudder.
the jet engine does not propel the heli forward. this in fact is bad as the heli has to hover at a awkward angle in order to counter the engine thrust. most helis have exhaust systems that that go toward the side so that no thrust will alter the flight characteristics. besides, the residual thrust of the turboshaft engine is quite low, not enough to propell the heli. the heli flies forward(or backward and sideways) by altering the cyclic controls. pitch the heli's nose down, and it moves forward. the same goes for all the other directions. -

whooooo! nice chopper! mean an badass!
this baby is hot.
whatever happened to the wolf though? or was it called kakhoum or someting like that? -
Ka-50/52 Alligator/Black Shark/Hokum? The Russian army selected this chopper over the Mi-28 Havoc. But i think they eventually purchased small numbers of Mi-28.

hokum yeah!Originally posted by eurofighter:Ka-50/52 Alligator/Black Shark/Hokum? The Russian army selected this chopper over the Mi-28 Havoc. But i think they eventually purchased small numbers of Mi-28.
ooo thats another badassed chopper! -
Yup the hokum. 2 variants, as eurofighter has said. Ka-50 werewolf, the single seat version and Ka-52 alligator which is the double-seater version. they've been marketing it, IIRC it just lost the turkish competition for a new attack heli.Originally posted by HENG@:whooooo! nice chopper! mean an badass!

the Mi-28 "longbow" havoc is cool. the radar provides search, targeting and guidance for the missile u see it carrying in the pic. they're either called the ataka or the vikhr; i keep confusing the two. kinda analogous to the APG-78 longbow radar/AGM-114L longbow hellfire combination.
that's all i know. could anyone provide more info on this russian longbow system? -
The Turkish chose the AH-1Z over the KA-52. But i heard they were unhappy with the cobra and they were still evualting the KA-52 with Israeli imputs.

Going a bit OT here, but I think that it's a pity they never went ahead with producing the Sikorsky S67 Blackhawk (not to be confused with the UH-60). That was a beautiful chopper, and watcing the test flight footage, this baby could fly. I have a nagging suspicion that the Mi-24 derived its troop-carrying gunship confuguration from the S67.

always love the communists' design, so out of western fashion, so mysterious and retro like. eg the sputnik, their fighters, subs, china's space programs etc. cool....

if i am not mistaken, this chopper has some sort of ejection system for its pilots. rotors blow away, then canopy blows... then airbags will activate at side of cockpit allowing pilot and copilot to roll out and parachute to safety...
I might have mistaken another chopper with this "ejection" system.
Correct me if i am.. =)
Btw.. its one mean cool Russian attack chopper -
The chopper with the ejection system is the Ka-50.Originally posted by Moonstriker:if i am not mistaken, this chopper has some sort of ejection system for its pilots. rotors blow away, then canopy blows... then airbags will activate at side of cockpit allowing pilot and copilot to roll out and parachute to safety...

excess tail rotor thrust is used for yaw, true, but it allows u to yaw one direction, if u need to go the other direction, u reduce the thrust
