Sabre Jet Engine: first start
The first start and initial test run of the Orenda type 14 turbojet that we have been working on for almost a
year now... you and me!
It's been a lot of work, and now it's all on the line as we crank this baby
up, hit the sparks and spray those combustors with Jet A.
It was an exciting and Exhausting
A special note: this is not a hot start, but fairly typical of the older
generations of turbojets to have flames
shoot out the tailpipe on startup.
The video response is from Burning Man participant Kunal Dovedy, and the
engine section he used is the exact one featured in my video "dropped into
a turbine engine".
Jet engine home made DIY with after burner
I wheeled my jet out for a clean, check and test run after being in storage
for 4 years and still running like the day it was built :-)
The after burner used 500ml of kerosine in around 23 seconds !
Tech stuff for those that are interested.......
The afterburner is made from a centre Exhaust resonator out of a Mazda 3.
Ignition is by a walter high energy igniter feeding two standard auto
plugs. (the ticking heard at the start)
A early Volvo mechanical fuel injection pump ( K jet-tronic) feeds 3 mirage
fighter jet fuel atomisers.
The turbine engine is based on a old Ford laser plain bearing turbo using LPG in a simple yet reliable
combustion. Injection is through a crossed drilled m6 bolt head - I have a
liquid fuel combustor but the gas is just so easy to use.
The digital instruments from the top are: RPM,EGT and Oil temp. Compressor
and oil temp are lower right.
The whole engine is fail safe , fuel is cut if any limits are exceeded. The
RPM uses a Banner brand fibre optic sensor feeding a frequency counter. The
reading is taken from the compressor nut.
The test frame was originally designed to supply a truck turbo based engine but marriage, house, kids saw
an end to building jets :-(
Thanks for watching !

4x4 Rock Crawler air suspension up & down suspension flex
4x4 Rock Crawler, Custom 4inch air ram suspension, 22in suspension travel,
forced suspension articulation capable with reverse pressure of the air
rams from on board air compressor, 49in brand new rims and IROK tires.
Drive line out of 1 ton Chevy truck. 350 Ci Chevy V8 runs good, 4sp Manual
trans with granny low, 205 transfer case in good shape, GM 14 bolt rear
end, dana 44 up front. Dual seats but has room for 4 seats. Here you can
see the suspension air rams getting pressurized and then deflated to lower
the frame. The orange line is my air supply which is inside the garage. A
completed system would contain an board air compressor so that you can
raise and lower the ride while in motion or as the driver wishes. This air
ram system allows for a very fun and comfortable ride.
How to build a TURBOJET ENGINE
HELLO GEEK WEEK
So this is the first in my trilogy of videos about building a turboJET engine from scrap.
This video is me building the jet then tomorrow i'll take you through the
simple maths and it is simple.
enjoy subscribe and see you next video.

Getting passed by a 25 Liberator at 110 mph
We were cruising about 50 mph when Wayne Duke came flying by at 110 mph in
a 25 Liberator with twin Mercury 300xs motors. Check out this video of my
25 Liberator reeling in the competition at the 2011 Toys for tots run! It
runs 113 on GPS with 34 cleavers on the rev limiters.
