amalahama Posted October 31, 2007 Posted October 31, 2007 mmmmm...I think most helicopters use Doppler Navigation instead INS because gyroscopes and accelerometers are sensible to vibrations... Maybe is Ka-50 an exception??
EvilBivol-1 Posted October 31, 2007 Posted October 31, 2007 No, the Ka-50 does have a doppler sensor to measure local velocity, but this isn't a self-contained navigation instrument. It's called "DISS" in Russian, which is an acronym for Doppler Speed and Drift Indicator in Russian. It looks like two light bulbs on the bottom rear of the fuselage, recessed to be horizontal when on the ground. You'll find the same instrument on the Mi-28 and Mi-26 as well. - EB [sIGPIC][/sIGPIC] Nothing is easy. Everything takes much longer. The Parable of Jane's A-10 Forum Rules
RvETito Posted October 31, 2007 Posted October 31, 2007 ... and Ka-32 ;) "See, to me that's a stupid instrument. It tells what your angle of attack is. If you don't know you shouldn't be flying." - Chuck Yeager, from the back seat of F-15D at age 89. =RvE=

Ratgnagna Posted November 2, 2007 Posted November 2, 2007 Can we start the engines with the rotor brake engaged? Thanks! :D Sorry for my poor english... :helpsmilie: Bye! ;)
EvilBivol-1 Posted November 2, 2007 Posted November 2, 2007 You can try... :D - EB [sIGPIC][/sIGPIC] Nothing is easy. Everything takes much longer. The Parable of Jane's A-10 Forum Rules

AlphaOneSix Posted November 2, 2007 Posted November 2, 2007 Can we start the engines with the rotor brake engaged? Good question! On many Russian helicopters, the rotor brake is very rudimentary (but hey, it works!) and there is a cutout switch so that if the rotor brake is applied at all, you cannot start the engines. It would not surprise me if the Ka-50 had the same type of rotor brake (Although, to be fair, I don't know if this is the case). Conversely, many Western helicopters have a hydraulic rotor brake that is much more complicated and prone to problems, but you can start the engines with the rotor brake engaged. The only reason to do so, however, is to allow the rotor to rapidly go from not moving to moving very quickly in the event of starting in high wind conditions (slow moving rotors are very susceptible to flapping in high wind conditions and could be damaged and could even possibly strike the tail boom). As a side effect, it makes some types of maintenance simpler (like engine washing) because the rotors won't start turning when you motor the engine, but that's not really a big deal. It's really just for starting in high winds.
Mugatu Posted November 3, 2007 Posted November 3, 2007 Great video Wags, must admit I was umming and arrring about buying black shark but I think you've swayed me. Love to see a video of what happens if you do things wrong, like starting with the rotor brake on, fuel off, or not enabling the power system correctly :)
