BVM Mig.15

Pete, so sorry to hear your sad news, I've PM'd you

Some pictures of the fitting of the tailpipe from last weekend. First job was to cut the tailpipe to the shape of the rear fuzz and fit the strengthening ring. Four maple blocks glued in, to hold the pipe in position.

Few more

Very tidy!

To protect the speed brake servos from heat I have wrapped another ceramic blanket around the tailpipe in their location. To secure I have used carbon tow wraps soaked in thin can.

Inner and outer tailpipe's fitted together, note the inner pipe is set back 25mm from the outer pipe as per the BVM instructions. On the turbine end, I have set inner pipe back 30mm from the cone as per the norm. This measurement is quite critical as too close to the turbine tail cone and it will suffocate the turbine and restrict power. If its too far away you run the risk of not collecting all the heat and flames from the turbine and in nanno seconds the model will be a fire ball.


In the last pick you can see the heat blanket through the speed brake aperture.
I will show details of the turbine installation when I get back on the mig over the weekend.
