Re: Why or why?
have you actually HEARD the P180? it is the loudest (and has very unique sonic signature) twin turboprop Ive ever witnessed coming in our out of SJ Mineta. Even the (also twin turboprop) Rutan Starship is quieter by a noticeable amount. Only seen that one twice.
turboshaft engines are light. electric motors can be close. But batteries still weigh more than kerosene. which means less cargo, higher wing loading, etc. Engineering challenges mostly but the biggest challenge is the bean counting. Not sure what technology is in the current or near state of the art that'll fix that. :(
