KNO3 and Sucrose 488
Date:1/27/01
Weather: Frequent gusts of wind, partly cloudy
Author: Benjamin
Type: Test flight
Acquired altitude: approx. 488 ft

I completed the 120V AC current to the igniter Test 2, and the homemade igniter ignited the propellant. There was a quick shower of sparks, then the fuel began to burn. The rocket had a very slow takeoff. It accelerated to an average speed of 24 mph from liftoff to 20 ft. of altitude. The actual speed at 20 ft has yet to be calculated. The rocket maintained thrust until approximately 2 seconds before apogee. The wind caused the rocket to drift about 100 yards from the launch site. The rocket reached apogee at approximately 488.89 vertical feet from the launch site. Previous rockets had a problem of exploding at about 50 feet because the core was too long, and the quick burning caused the chamber pressure to be greater than the casing could handle. This rocket had the same amount of fuel as the previous rockets but the difference was in the nozzle and the length of the core. The nozzle on the original rockets was not angled at all, but on Test 2, the nozzle was angled in all directions about 15 degrees (the throat of the nozzle was the same diameter). Also, the core of this rocket was only half the distance from the fuel to the plug. Because the core of these rockets is cut down by half, the fuel burns quickly for takeoff, but then slows down to maintain the pressure needed for a nice, slower burn. 488.89 feet is an amazing altitude compared to the previous tests. After a year of building rocket engines, this is the most successful launch of any of them. Because this was a test of an engine, it was launched strapped to a dowel rod, rather than being launched in a rocket, and because we did not now if the rocket would detonate, or lift off at all, we decided not to waste a model. Now that we have witnessed the performance of these engines, though, we hope for some very successful launches in the near future.
