Ciao a tutti,
sono riuscito finalmente a reperire il grandissimo video e progetto di questo fantastico STS.
Quoto la composizione dello stack dalla pagina del costruttore:
"[i]The Orbiter is built mostly of balsa, with a vac-formed nose (the orbiter was built in 1984, upgraded for this boilerplate).
3 Channel R/C: Elevons for pitch control, movable rudder for directional control, and 3rd servo for Orbiter sep from ET (sep commanded by pilot). Glide mass 210 grams.
ET bottom flies on an F25 expendable motor.
There is an A3 motor in the Orbiter for “staging” (OMS burn simulation).
Vac-formed ET Nose has a Flight Computer inside which senses Liftoff, Burnout, and Orbiter sep.
At liftoff a flight program begins, when burnout is sensed the computer commands a servo in the ET to separate the SRB’s. Computer waits for pilot to sep the Orbiter by R/C, then 1 second after Orbiter sep the computer fires the primary ejection charge. The Orbiter ignites an A3 motor for “staging” when it separates from the ET.
SRB’s have wind-up Timers in their noses which start timing when the SRB’s are sepped from the ET. About 2 seconds after sep from ET the Timer releases a rubber band driven rod to push off the nose cone and deploy the recovery system. Each SRB has a single fin oriented 45 degrees below the Orbiter wing, partially aiding pitch stability but mostly proving ventral fin area to reduce yaw/roll coupling from the orbiter vertical tail (fin/rudder).
Liftoff mass of the 1998 boilerplate is about 1000 grams, right a the FAI weight limit for S7 (scale). However, there is room for reducing mass such as using fiberglass tubes for the ET and SRB’s, and we begun studying the feasibility of composite construction of the orbiter. Such reduction in mass will have to be done to allow for the weight to be added by finishing, paint, and detailing that the boilerplate has not had.[/i]
Ho voluto condividere questa pagina e questi video con voi perchè sono datati ormai 1998 e potrebbero essere persi.
Anche perchè il sito non viene aggiornato da anni ormai.

Grazie Ricky per l’aiuto (:
