Zagi rocket
This is a 1.5m zagi with a pressure vessel clamped to the fuse.
The vessel is filled half with water
and then pumped to 14 bar
The front of the vessel has a parachute.
When the pressure drops the clamps release the fuselage
and the parachute deploys
and the launch begins
The thrust at 14 bar was calculated at around 100kgs
static.
The vessel is carbon fibre made in house.

Keeping your spoon from being used to mix resin
can be tough.

Talking Tugs
The work horses of silverton gliding club
2m stick on the right.
It has had many tugs with gliders from 1.5m to the Asw 27 of Antony Van zyl
shown below.
Pre-flight checks and connection of tow rope.
Take up the slack, Wind direction check
Wings level and constant climb rate.
Time to ease back on throttle on the tug.
The glider should not follow the direction of the tug exactly, this makes slack in the line and then sudden tension. Resulting in the glider swinging from side to side.
If the tug turns right the glider should slide out left first and then to the right.
This keeps the distance between the tug and glider and tension on the line.
Shown below.
Shown below.
We have had tows with just after takeoff both the tug and glider doing a right hand roll and then a left.
The glider was epp and not in the 6m class.
