Rocket Launch this past weekend

Post by dell »

So this is a drone view of the big black rocket I was working on during the last Video Bat Chat. The rocket is about 6 feet tall and I launched it on an H148 Red. The motor has a brilliant red flame which is not so obvious from this angle. It was quite cloudy and we are not allowed to launch into clouds, so I had to keep it under the 2,500 foot cloud ceiling. The rocket went to 1,210 feet.

H148 Red

I found some videos of past launches and will post links later.

Another video of my rocket club from 2 years ago. This was a low and mid power launch. The audio is quite entertaining in places.

5-5-18 Rocket Launch

Some highlights:

My Sammy-Pooh at 1:40

At 2:40 is a big rocket on a G motor.

At 3:19 you see three of my rockets waiting to be launched. All are red and black. On the left is Sheesh Kabob. The next one is Square Kabob, and the third one is Swoosh Kabob.

Another one of my rockets at 6:08. I call this one the Indifferent Whatever.

At 6:28 a chuffing liftoff followed by a "lawn dart" landing.

Drag race at 7:00 with a second camera at 7:21 showing the chuffing

Some chuffing at 7:40

My Bluebird of Happiness at 7:58

A glider that didn't glide very much at 8:56

Three motor rocket at 10:10

My F.A.B. (named for a phrase from the Thunderbirds) at 11:26. This is a mish mash of parts slapped together with pieces of the body missing, a chewed up nose cone, no matching fins and it flies perfectly straight (notice that there is almost no rotation on the way up)

Me standing in the field at 12:27

Bad flight at 13:31

Rocket ejected the motor at 14:00 (you can hear it hit a car)

My Photon Probe at 14:13. The ejection charge didn't eject the parachute.

Bad launch at 14:41

Interesting Flights

2017 "Interesting Launches"

You will hear a lot of "oh no!"

One of the things we often say, "The up part is easy (usually), the down part is where you can have problems".

0:12 Motor explodes

0:24 My Sidewinder scale missile not flying very straight. But it lays out flat at the end for a great finish.

2:12 Daisy the Rocket Dog. She LOVED barking at rockets launching.

The first and only "flight" of my Estes V-2 at 4:27. Motor failure.

5:32 Good flight, but it lands in the creek.

6:32 Don't blink! (rocket on far right)

That was fun to watch. Yeah, the comments from sidelines were fun to listen to. Especially on those "Oh No" moments.
Who knew "chuffing" could be so entertaining?
That looks like a fun day out.

"Oh no!" was a personal highlight! Very cool to see after hearing your descriptions and insights on Video Bat-Chat!

Here is a video of Justin's three attempts to get his level 2 certification. The third attempt was successful. The second attempt had an onboard camera and you can see that video from liftoff to parachute deployment.

Loving the videos. The onboard camera was cool. The fifteen foot Merlin was insane.

This launch took place in 2009 in Maryland. It is a huge model rocket.

That was a thing of beauty. Made my morning. Wish I could have seen it in person!

I have no idea who took this video, but it is pretty interesting. Warning: a lot of spinning on the way down!

Four cameras capture the flight. One shows liftoff from near the pad. The second shows liftoff from further back. The third camera is mounted on the lower section of the second (sustainer) stage. It will stay pointing down most of the flight. This camera is recording an electronic voice that calls out altitude and other information during the flight. The fourth camera is mounted near the top of the rocket and will point down before apogee and then point up after apogee as the rocket will split into two parts that are tethered together. At apogee the flight computer will fire a small explosive charge to push the upper section of the sustainer off the lower section and deploy the drogue chute. Separating the two sections of the rocket creates a lot of drag as the rocket descends.

The drogue parachute main purpose is to keep the upper and lower parts of the rocket away from each other to prevent damage and keep the parachute from getting caught on part of the rocket or tangled in the tether line. The drogue slows the rocket's descent a little bit, but that isn't the purpose of the chute.

the main chute is deployed around 700 feet and reduces the speed of the rocket considerably so it can land without damage.

So this guy built an electronics package for a rocket. He found someone to fly it for him and the flight was let's just say less than optimal. There are several terms we use for landings like this; lawn dart, shovel recovery, trashbag recovery... you get the idea. And as we rocketeers say, the up part is easy, the down part is hard.
