Camp Skärgården 1979 -Hercules

In september the clubs biggest PVC+AP propelled rocket - HERCULES- was ready to be launched from an island far out in the archipelago of Stockholm. The motor was an upscale of the wellknown ODEN-motor. Hercules was successfully tested earlier and caontained 8.5 kg propellant. With a little light instrumentcapsule it was capable of reaching over 10 km in altitude.

But at liftoff the rocket ignited as expected and lifted to abaout 1 meter in the tower and then exploded. The investigation after found that we had reached the limit of sclability for the ODEN-concept. Hercules mainproblem was bad casebounding of the propellant to the outer wall of the motortube.


Instrument was a transmitter with measuring of burningtime and flyingtime.

Assembled instrumentsection with spiral-antenna integrated with the nosecone.

Hercules is prepared in the launchingtower this beautiful septemberday

The rocket Herkules lifted 1 meter, and then exploded in the tower. The explosion was obtained by bad case-bounding. We hade reached the scalabilitylimit with that design. Expected altitude was 8,5 km.

To reach the launchingsite we had to use a Russian built Volga (Swedish brand=ALU-85) hydrofoil for transportation. It loaded 200 kg equipment and 5 persons and is a superb boat.

Full speed in the cold morning

A very nice trip with the hydrofoil

Here the rest of the members arrive with the hydrofoil to the launchingarea on the small island. The hydrofoil is made in Russia under the name of "VOLGA". Read much more about Russian hydrofoils here
