Just came away from a meeting with the aluminum end housing coalition.
IE. Foundry.. machine shop.. pattern maker.
They have come up with a very VERY good way of positively locking the

through

hardened steel wear surfaces into the aluminum castings. We are
all very excited about the prospect of a 150 pound rotary engine
putting out 250 HP and doing it with no fuel burn penalty.
Now if I can get 15 pounds out of a 3:1 gear box we
will have one heck of an aircraft engine.

Ya know... a 400 hp three rotor Harmon Rocket or F1 Rocket would

kick so

many butts it would be just silly      P-)

Why stop at 400 HP? A 900 HP three rotor has been done on the dyno. Would

work

great in a Nemesis Next for Reno or most other 100 mile cross country air

racing.

I think it would beat most small single engine turbines airplanes in

a 1000

to

1500 mile race simply because it would not have to stop for fuel and it

would

generate way more power up high.

Two out of the four end housings are aluminum in this RB engine pictured

below.

There also is that sprint car water pump I mentioned in a few

messages back.

    YOU GUYS BETTER QUIT TALKING LIKE THIS, I'M START'IN TO DROOL ON MY KEY
BOARD.   MY JUMP PLANE (C-182) IS CRYING FOR A FEW MORE PONIES (300+)AND
SOMETHING THAT DOESN'T SHOCK COOL ON THE WAY DOWN (SLIGHTLY FASTER THAN MY
GUYS IN FREEFALL).
"IF YOU BUILD IT, THEY WILL JUMP"  they are starting to eye my Lancair

with a

sawzall, they think speed = climb (sorta).  skydoc

I got an old skydiving buddy that has had his fun with a Beech 18 and has
it for sale.  Wouldn't it be fun to put a pair of 600 hp turbo three-rotors
in that and see how it would do.  Give the PT6-20 Westwinds (converted
B-18) a run for their money you would!  With a competent pilot that would
be a money making machine.
