University team looking for advice: Movable fins or thrust vector . . . Question Hi everyone! We’re a university team just getting started with building model rockets, and one of our main goals is to develop an active control system We’re currently debating between using movable fins (canards) or thrust vector control (TVC)
Fineness and Stability Margin in OpenRocket - Rocketry Forum I have a tall thin rocket with a fineness (aka aspect ratio or length to diameter ratio) of ~26 (80” long 3 1” diameter) As currently configured, it has a stability margin of 3 7 14 6% in OpenRocket I am trying to answer the age-old question is if this rocket is over-stable The only “rule of
Designing a Rocket for a (considerably) High Altitude Flight Looking at your rocket, I'm thinking you need a bigger rocket, and probably a few more years of experience flying high power rockets Even with the biggest LOKI motor, the M1378, you would still come up short by a few hundred feet That motor is almost 4 ft long Your design would not be long enough to hold that motor, and would probably not

Maximum height of viewable rocket flight??? | Rocketry Forum - Model . . . There are a number of factors that affect the observation height of a rocket Observations looking directly up with sun and cloud cover will limit the observable height to 4-5K ft Observing the same rocket from 1000 ft distance with the sun at your back will increase the observable height by 25-35%
New Method for Parachute Deployment? Deployment by Rocket Extraction . . . These either requiere the rocket to have a certainly speed to work or a heavy supporting structure to enable the deployments If the objective is to minimize weight and for the deployment to occur as far and as close at apogee as possible, wouldn't this Rocket Extraction method be very practical? I would love to know your opinion Thank you!
