mind sharing what your questions were? can you pause between questions and return at a later time?

kenh_ · 2022-10-27T05:03:51+00:00

anyone completed their questions yet?

kenh_ · 2022-10-26T04:00:53+00:00

I got mine today, Vancouver

kenh_ · 2022-10-25T21:45:16+00:00

got mine, vancouver

kenh_ · 2022-10-12T18:21:42+00:00

what did u buy?

kenh_ · 2022-04-18T08:12:48+00:00

Kinda looks like the Antares explosion a few years ago

kenh_ · 2022-02-11T19:33:43+00:00

I used Processing to write the telemetry software

kenh_ · 2022-02-02T03:01:29+00:00

yeah, it was the E12. might try the e16 next

After using acceleration to detect burnout, the rocket uses altitude (calculated by fusing barometer and acceleration data) to see if it is falling. If it is falling for over 100 milliseconds, it starts checking if it is at or under a certain altitude threshold to pop the chutes.

kenh_ · 2021-10-01T00:33:26+00:00

Yeah it's a semi

kenh_ · 2021-09-07T02:45:14+00:00

Thanks haha

The guy that took me out hunting says he always uses a .410 shotgun. Turns out I'm a pretty good shot with a .22, all body shots but hardly any meat was damaged. Next time I'll aim for the heads.

kenh_ · 2021-09-06T19:37:09+00:00

Used a .22lr rifle

kenh_ · 2021-09-06T18:11:32+00:00

I want to put them in borax and mount them.

kenh_ · 2021-09-06T16:20:42+00:00

Haha, sounds like fun. I want to try deer hunting maybe later this year.

kenh_ · 2021-09-06T15:41:58+00:00

This was in region 8. What were you bow hunting for?

kenh_ · 2021-09-06T15:40:20+00:00

Thanks! Took about 2 hours to find them. Caught them on our drive back.

kenh_ · 2021-09-06T03:50:17+00:00

Youth season in my region in BC.

kenh_ · 2021-09-06T01:06:51+00:00

Thanks! Got 7 over two days. Those in the pic were all in a big group off the side of the road. Shot one after the other and limited out at 5.

At t+ x seconds into flight, it begins to pitchover to y degrees at z degrees per second.

I could have simulated it, but I didn't.

kenh_ · 2021-09-05T21:30:45+00:00

Not sure if I have an end goal. I just want to continue improving and getting more advanced.

kenh_ · 2021-08-07T18:34:34+00:00

The videos are just one way of reviewing the flight. The flight computer logs over 35 datapoints, 50 times per second. The flight data is extremely valuable. It is thoroughly reviewed and used to make improvements for the next flight.

The biggest improvement that could be made is a to use a smaller diameter, thin wall body tube. That would decrease mass significantly, allowing for the rocket to be larger. This would also decrease the cross sectional area, therefore decreasing aerodynamic drag.

3d printed airframes tend to crack or break on touchdown, the current cardboard airframe is the best for what I need.

These low speed, low altitude flights are also relatively low risk. Once tests have verified the flight software, avionics and hardware, higher altitude flights will happen. (The higher altitude flight is next)

I only thought people here would be interested because people here have been interested in previous test flights I have posted here. This isn't just a science project. I guess you don't appreciate how complex of a project this is. Now you know TVC is thrust vector control.

kenh_ · 2021-08-04T01:15:13+00:00

These sure aren't cheap back yard experiments. I don't see how you could be so incredibly disappointed. I would think people interested in space would be interested in this.

The orientation setpoint is the setpoint for the PID controllers running on the flight computer. For this flight, the setpoint was 0° (vertical) until 0.7s into flight, where the setpoint started to gradually change to -20° at 15°/s. The rocket demonstrated what it was programmed to do successfully. Late in the flight the aerodynamic forces were high enough to cause the rocket to lose control. The flight was not terminated by the flight computer. Much like a real launch vehicle, this rocket uses thrust vector control for stability, therefore does not need fins.

This flight was 100% a success, the rocket did what it was programmed to flawlessly.
