This is my first post, and it's
mostly a hypothetical issue, so go easy on me:
As the regulations for Light Sport
and Ultralights planes read, the plane has to have a "single reciprocating
engine".
Does that also include an unspoken
understanding that the engine may only drive a single propeller? (In some
situations, possibly for prop clearance reasons, two smaller props would work
better than a single larger one.)
Conversely, how the FAA would view
joining two (originally) separate engines together to drive a single
prop? What I'm thinking here is that if of one quit in flight then you'd
still have at least some power to work with - but without the added difficulty
of off-center thrust (which I'm guessing is the purpose of the 1-engine
requirement in the first place).
The added complexity might make it more trouble than it was
worth. -But hey, I figure the first part of creating an experimental
aircraft is figuring out if it's technically and legally possible in the
first place!
Thanks!
