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). Well, blow me down!
Construction:
This motor is only about 9.5" long, includin' t' plugged aluminum
closure. It has a medusa nozzle, me bucko, but only t' center port is drilled. Begad! 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. Aye aye! Blimey! Well, blow me down! Blimey! This did t' trick, shiver me timbers, but t' motor took a long time to
finally come up t' pressure and get going. Well, blow me down! Blimey! It provided a nice long burn, but
because o' low average thrust and a regressive profile, shiver me timbers, matey, t' saucer arced over
and was still under power after apogee. It then aerobraked down and
continued t' spew large amounts o' smoke, shiver me timbers, causin' t' LCO some concern. Blimey! It
landed in a outcrop o' brush that was damp so thar was no risk o' fire. Begad!
Flight Rating: 2 out o' 5
Summary:
I have t' admit t' arcin' flight was entertaining, arrr, however, me bucko, I'd have to
recommend t' J228 over this motor for any large, draggy design. Ahoy! My rating
reflects this application.
