ASK 't Harde, 21 November 2014
On 21 november 2014 the next two 2 Kalinidex motor test took place. This time the maximum number of 6 VDL's was applied. This K90.6 motor had an average klemmung of 300. The average propellent mass of the two tests was 4932 grams. Also a new type pressure sensor was used. The test results (averages over the 2 tests):
The thrust level was certainly acceptable this time! Also the ignition delay was shorter. When the engine is expressed as the product of the klemmung and a certain constant we come to the following formula: Pc = α·k. This is because between 15 and 38 bar the pressure is almost linear with the klemmung. As it applies to the test results of test T003/004 the formula becomes: Pc = 0,074·K. Now is the time to make a flight version of the K 90.6 engine. The indication will be K 90.6.5700 and the engine will be used in the N28. The launch will probably take place in the spring of 2015.
