[@AirCommandRockets]

Yup, we intend to do that. We've had a closer look at it, and it is pretty noisy in the boost part of it. The peak velocity data doesn't seem quite right from the altimeter. We are also comparing it to simulations to give us a more representative value.

My most sophisticated one had a clear plastic "capsule" with a seated astronaut inside and a parachute in the capsule base. It worked great, It might have gone up 100' but in 1962 I had no way to determine altitude. I wasn't smart enough at the time to use a protractor/pencil pointer and trigonometry 😎

[@AirCommandRockets]

Thanks Chris. We're really keen to start working on the first stage and it's launcher now. We've been having lots of discussions about those, but it was important to get the sustainer flying first so that we could find out how it needs to be supported and how to protect the first stage from the exhaust of the sustainer. There is host of good challenges to those.

[@chrisville25]

@@AirCommandRockets Now correct me if I'm wrong, but we should expect an altitude loss from sustainer of at least 1/3? (On fully built horizon)

[@AirCommandRockets]

We haven't done the final simulations yet, as a lot will depend on the final weight of the booster and we won't know that until we've built it. I would expect the booster to add about 30%-40% more altitude to the sustainer. The trickiest part is going to be to get it to stage vertically, more often then not the second stage is released away from vertical.

[@riccardodipietro4362]

Hi, I have recently started doing water rockets with my AP Calculus class. I am looking for an altimeter that would give us the data that your altimeter was able to give you, height versus time graph. With this graph, we will be able to do quite a few things using calculus with this data. Is there anyway you can point me in the right direction of finding such an altimeter? Thanks! Mr. Washington

[@AirCommandRockets]

Hi Mr. Washington, The altimeters to look for are logging altimeters that record the entire flight. Some altimeters will only record a peak altitude which is not that useful for your class. Here are a three I would recommend: jollylogic.com/products/altimeterthree/ This logs the entire flight and you can download the data via your phone. Also we've used the zLog altimeters quite a bit: www.hexpertsystems.com/zlog/ . I can also recommend the Stratologger CF www.perfectflite.com/SLCF.html. They all record data but use different software to download the data from the altimeters. There are a number of different re-sellers of all of these so Google search for these to see who has them in stock. There are many others, these are just the ones we've had direct experience with.

Question does soap help the performance of the rocket

[@AirCommandRockets]

[@spaceaddict5484]

Is this technically more like a gun than a rocket? In a sense where a gun all the potential energy is released at once into kinetic, which starts at its fastest speed then slows. Where a rocket releases its energy over a period of time so it starts slow then accelerates until its out of fuel. Obviously its a rocket.. but I mean, did you alter the thing so it keeps accelerating by adding some sort of extra stage or something?

[@AirCommandRockets]

I would say not. A gun uses a barrel to accelerate the projectile with gasses pushing on the outside of the projectile. A rocket's acceleration comes from expelling the gases from the inside, no barrel is needed.

[@peetiegonzalez1845]

Great video and achievement. I was curious... what kind of water are you using as propellant? It occurred to me that a more dense propellant such as supersaturated salt water, or water with Sodium Tungstate dissolved in it would give you automatic performance gains, without fouling the environment. Do you use any of these?

[@AirCommandRockets]

Making the liquid more dense doesn't necessarily give you more altitude, although you get higher thrust, you also have more weight (heavier liquid still in the rocket) to lift with that thrust. Here is a video where we compare different liquid densities: kzbin.info/www/bejne/fKaWo3yfhd6SZ5o The gas on the other hand should be more dense for better performance. Some people fly with CO2 that helps the performance.

[@gillesbkf4315]

It’s just a fish eye effect, you can’t really see the curvature of the earth at 1000m high

[@Mongo63a]

Would a nozzle size that was smaller for the air only segment give more/longer thrust? Could you have a nozzle inside that actually floats on top of the water column and seats as the last of the water is expended reducing the diameter of the nozzle cross sectional area? BTW why shampoo, lubrication or change is surface tension? Can't wait for your multi stage launches.

[@AirCommandRockets]

These types of nozzles have been used on water rockets and are called a T-nozzle. Normally they sit on top of the launch tube and then settle at the bottom of the big nozzle when the rocket leaves the launch tube. They don't float on top of the water though. The shampoo was mainly added to try to improve the cooling inside the rocket. We were hoping that the huge surface area created by the bubbles should help with cooling the air internally as it compresses.
