Should also be noted that any rotation along the bridle attachment point axis is perfectly acceptable and won't affect performance to a degree that I care about currently.
If the velocity is high and the drag is low, would conditions be more optimal? Less shaking, etc? A scaled down test with a 3 axis gyro might have to happen in an "inert" object. Presumably this data could be used and scaled.
I have to increase the initial velocity to 110 m/s to get to the appropriate altitude using that calculator. Hmm.. A drag coefficient of 0.5 should be pretty close as that's what a sphere is.(roughly)
There have been some finned designs in past that have worked, but I really wanted to try the parachute idea :) The moment of inertia for a solid sphere of this size and mass is 0.10498 kg m2. Where do I go from here?
Reading about moment of inertia right now. We'll have to assume that the object's mass distribution is even. To minimize jerk and oscillations, I'm thinking using the lowest amount of drag for as long as reasonably possible would be optimal. Is this correct? Another person on a forum more...
It's an aerial shell(not bomb) that is to be built onsite(legally) at an event that has all the required permits. The problem with deploying the parachute after apogee, is that it causes a significant timing problem in the event that the parachute fails. To avoid affecting shell performance in...
How do I determine how much drag is required to orient a spinning spherical projectile with a small parachute just before apogee? The projectile is going straight up. The parachute will not be deployed until around 6.5 seconds into flight when the object is traveling at 14.2 m/s. This isn't a...
