Tiny Liquid First Flight

Being an F motor with only 40 grams of propellant, I am pretty sure it is the smallest amateur liquid ever to fly.

I love how easy you can see the tiny mach diamonds

Congratulations on a great achievement! This is a very simple and clean design!

[YoungPhysicistsClub]

You have no idea how impressive this is

[mfve]

High five and congrats man, I was waiting for this video. You are the record holder!

[sachitshastri]

Congratulations! It was extremely impressive. Loved to see the parachute deploy as well :)

[KirtikSoni]

If you pause at 0:44 you can see mach diamonds! Impressive

[Les__Mack]

Wow. I've daydreamed about making one of these. Very nice job!

[rcketplumber]

Well done, you've made a motor the size of an igniter! That a tough problem.

[stavrosTX]

Very cool, can't wait to see what is next!

[zachyt]

One can only do a static test, but you could make an actual rocket! Also the shock diamonds look badass

[JWilsonCollege]

Awesome first flight!! Seems like it may have pulled the gravity turn a bit early though.

[baldwin]

i think you need to correct the centre of mass

[nejcjug]

how much did you presurize oxidizer tank

[Kerballistic]

You got some pretty nice mach diamonds there...

Super cool stuff! Need your wise advice on one idea, I'd love to get your take on it.

So, it's got two modes: a low-speed mode using Electric Ducted Fans (EDF), and a high-speed mode where it switches to a solid rocket engine burning 3D-printed ABS plastic using air from EDF to burn, it is similar to using EDF with afterburner but how about trying with solid rocket fuel. Pretty wild, right? The idea is to transition smoothly between these modes for more control and power.

Here's the breakdown:

EDF for cruising around at low speeds.
A Tesla valve to keep the combustion stuff from messing up the EDFs.
Adjustable airflow part inspired by the SR-71 Blackbird – it's all about getting the air flow just right for the high-speed mode.
The solid rocket engine – using ABS plastic to make it go boom in a controlled way, 3d printing required to create profile which maximizes contact area with air from EDF.
In high-speed mode, it's like the EDF and rocket engine team up for some serious thrust.
We can actually control the thrust and turn this bad boy on and off, unlike traditional solid rocket engines.

What do you think? Any advice on using ABS plastic for the fuel or tweaking the airflow setup? Would appreciate any tips or insights you have.

Cheers for the inspo, and can't wait to hear your thoughts!

Dude it’s like those Russian anti ship missle so cool 👏👏👏👏👏👏👏👏👏

[staticmin]

mach diamonds.... awesome, fricken awesome ;-)

[hybridfreak]

Awesome work! Maybe you can increase combustion efficiency and ISP using something like Contrail rockets CNVA? They use tangential holes creating a swirl in the oxidizer flowing from the tank to the injector which then creates a vortex in the combustion chamber that mixes things quite well. Like on Monotube hybrids a lot of nitrous and fuel will go straight from injector to nozzle without properly burning in your design.

Nice! Not a lot of thrust (and not very stable) but it's still decent! Might become even more effective idk
