The Army Apache has a net turnover angle of less than 20 degrees and would be unsuitable for deck operations. The net turnover angle is the static turnover angle less the movement of the center of gravity due to oleo and tire compression on a moving deck. Wind forces also affect aircraft turnover and need to be considered. For purposes of this study a net turnover angle of 36 degrees was desired which leaves a conservative margin for landing gear dynamics and wind effects. Using the criteria for a static turnover angle of a minimum of 32 degrees and a maximum of 38 degrees a study of different landing gears was studied and a tricycle gear selected
maybe,Grey Havoc said:With all the recent and ongoing developments, perhaps the time of the Sea Apache has come again.
A folded SH-60B is 3.2 m wide by 12.5 m long. That's actually a bit smaller than the footprint of the Sea Apache shown above, especially with the rotor folded with two blades forward and two aft as shown in the drawing. (4.17 m wide by 11.6 m long) If they adopted a blade fold that put all four blades aft, Sea Apache would still be something like 11.6 m long, only a bit shorter than a Seahawk. No way you can get Apaches two for one in place of Seahawk.Brickmuppet said:Dimensionally, how did a stowed Apache compare to a stowed Seahawk?
I've tried unsuccessfully to find dimensions for stowed helicopters find dimensions for some time.
Arguably, Seahawk wouldn't be as survivable as a dedicated gunship such as the Sea Apache. In fact you could even argue that the Seahawks only real advantage over a dedicated gunship is that it can carry troops.TomS said:Which of course means that there's no clear role for this naval attack helo now. Seahawk is (finally) being widely armed with Hellfire and door guns. Its only real drawback compared to Sea Apache in the marine environment is the smaller missile load, which is more than compensated for by the increased versatility of the SH-60.
Also, ASW equipment, 360-degree search radar, etc.Grey Havoc said:Arguably, Seahawk wouldn't be as survivable as a dedicated gunship such as the Sea Apache. In fact you could even argue that the Seahawks only real advantage over a dedicated gunship is that it can carry troops.
