ASK 't Harde, 19 September 2014
On 19 september 2014 the two first Kalinidex motor tests were held. The purpose of these tests was to prove that the new Kalinidex concept was the right choice. This was indeed the case! The test engine used was a K90.4 type and was therefore equipped with 4 VDL's. With a throat diameter of 25 mm the average klemmung reaches 200. The average propellant mass of the 2 tests was 3239 grams.
The testresult (average from 2 tests):
|Maximum pressure||:||pressure measurement failed|
|thrust coëfficiënt||:||unable to determine beacause the preasure meassurement failed|
At the next tests we will have to use another pressure sensor. Also the shortening of the ignition delay needs attention. A calculated reconstruction of the engine pressure showed that this pressure should be around 14-15 Bar. That is too low for a rocket flight. The engine pressure, and therfore the klemmung, must be higher at the next test.
