2023-05-23 The Estes Logo Rocket
You know... the Estes logo. It's "That" Rocket.
Launch Report: Estes Logo Model Rocket
Date: 2024-05-30
Background
This is the maiden launch of this scratch build / design model rocket
On Site Preparations
I did not use any wadding for this rear eject spool design. There’s simply no room.
For a parachute I used a 18” Nylon chute.
This launch will use a E20-4W Composite motor. This is Aerotech’s “White Lightning” propellant which.
The supplied Aerotech igniter was used.
The rocket was slid onto the 5/16" launch rod and the controller wires were attached to the igniter leads.
Launch
Wind was out of the East and was about 4 mph at the most.
John stated the sky was clear - launch site was clear and did the countdown: 5-4-3-2-1. Teresa pushed the button on the launch controller.
The motor ignited and the rocket leaped off the pad. It flew stable upward but then went unstable heading toward the South where it ground hit, 128 feet South of the launch horse. The delay was still burning, and the rocket ejected its chute.
Condition of rocket after the flight
The rocket was uninjured and flight ready. "Hell-For-Stout" construction paid it forward.
Conclusions
This rocket has a calculated stability of 0.059 calibers. With the base drag hack it has a calculated stability of 1.16.
A string swing test was performed and the rocket passed that test.
What I learned
There must be some other phenomenon affecting the flight of this rocket?
