This post is going to display a lot of ignorance, but ....
My limited understanding is that;
- It is extremely expensive to bring out a totally new helicopter.
- The S-92 is a derivative of the Blackhawk and the R-44 is a derivative of the R-22, and this results in a much lower cost of certification.
- Carson has just brought out composite blades for the S-61 that can lift 2000 lbs more then the original metal blades
- Carson is looking at expanding the envelope for S-61's with composite blades.
- Carson is developing new tail rotor blades for the S-61.
- Carson is looking at avenues of aerodynamic drag reduction for the S-92.
OK. The dumb question.
Why is it not possible or practical for a company that makes an old design of certified helicopter with two seats, such as the Brantly, to step by step, just like Carson, change and improve the helicopter till it no longer resembles the original.
Would this be a viable way to develop an economical helicopter that could eventually compete with the R-22 as a trainer.
