SENTRA SRB
In-flight pod release rocket!!
|
|
SENTRA SRB is a side-staged pod release
rocket. It offers dramatic in-flight action in conjunction with the high
performance of the main central rocket. The Interchange mount in the main
body offers many motor options. Much like the Space Shuttle, SENTRA SRB
releases the pods in mid-powered flight upon booster motor burnout. This is
why very short to zero delay motors are used in the side pods. Long burn
central motors are best for good post boost performance. Includes 29mm,
3-29mm, 4-24mm interchange mounts.
This efficient design has a drag reduction shrouds on the booster stages.
All three stages can recover by parachute and the rocket has good motor
versatility, so it is a real pleasure to build and fly. It uses
Discontinuous Staging™ to permit parachute recovery of both stages.
Discontinuous Staging™ is used on designs where the stages have no
direct flame path and permits the lower stage to be recovered by parachute.

| SENTRA SRB
can be slightly modified to
accept new dual deployment systems and altimiters. The payload
can be deployed on both sides of
the coupler or both sides of the payload tube. This rocket is
recomended for science work. It flies surprisingly well on 2 F80-4 to G30-4.
Best flights are with
USR
2 H240-4 to I65-8. SENTRA SRB has been successfully tested with
as
high of
power as 2 H160 to K250-12 with a payload. Its very strong and lightweight
construction makes
it fly surprisingly high
compared
to other rocket kit brands. Test it for yourself!
