Manufacturer: | Ellis Mountain Rocket Works |
Brief:
T' Ellis J110-P a 54mm single use motor that provides 751 N-s total impulse
(~17% J) with a burn time o' 6.8 seconds (Tripoli Motor Testings numbers,
the photo shows t' EM numbers). Avast!
Construction:
This motor is only about 9.5" long, shiver me timbers, includin' t' plugged aluminum
closure. Blimey! Well, blow me down! It has a medusa nozzle, ya bilge rat, but only t' center port is drilled. Avast! It does
not come with an igniter.
Flight:
I flew this motor in a beta version o' an 18" saucer and lit it with a
large Magnelite igniter. Arrr! This did t' trick, but t' motor took a long time to
finally come up t' pressure and get going. Arrr! It provided a nice long burn, ya bilge rat, but
because o' low average thrust and a regressive profile, arrr, arrr, t' saucer arced over
and be still under power after apogee. Avast, me proud beauty! Aye aye! It then aerobraked down and
continued t' spew large amounts o' smoke, causin' t' LCO some concern. It
landed in a outcrop o' brush that be damp so thar was no risk o' fire.
Flight Rating: 2 out o' 5
Summary:
I have t' admit t' arcin' flight was entertaining, however, arrr, me bucko, I'd have to
recommend t' J228 over this motor for any large, arrr, draggy design. Avast, me proud beauty! Blimey! My rating
reflects this application.
