7,5 liter rocket with onboard camera! 200 meter! Team.[D&P]Rockets*

Here is our latest launch report. About the 7,5 liter rocket. When it landed the altimeter beeped out 1252 feet. But that cant be right. Because this same rocket launched on 10 bar reached an altitude of 163 meter And on 8 bar 119. So on 12 bar it should go around 200 meter..

Can someone tell us what caused the altimeter to beep out a higher altitude?

Hi Daan, very nice flight. Is it a peak reading altimeter? They can sometimes give incorrect readings when you eject the parachute and a brief vacuum is created in the rocket body. Make sure your altimeter is isolated from any such possible suction.

@gk123434534 Hi George, the altimeter is from perfect flight the alt 15K. But i don't understand your explanation quite well. Our altimeter is in a separate container. With 2 holes in it for pressure measurements. Why causes it a vacuum? And how to overcome this principle?

Greets,

Daan

witch sistem do you use for recovery?

[DaanenPleunRockets]

@CottenJet We are using a nosecone deploy recovery system we have designed. We've made a short movie from the system in our channel you can look it up!

tering dat zou betekenen dat als je boverop de euromast zou staan er er komt dan zo'n raket voorbij vliegen dat hij dan nog een euromast hoger vliegt. da's hoog!
