v12 RC Engine Model Construction
v-12 engine with compressed air injection,hand made using taditional
methods:12 cm3 of displacement,the diameter of the cyllinder is 11,3 mm,the
stroke of the pistons 10mm,it works with only 0,1kg/cm2.Is constructed with
stainless steel,aluminum and bronze.Patelo dedicate this engine to his
grandchildren:Sara,Carmen,Jose and Pablo.This engine is for
education,exhibitons,etc.,that is the reason to work with compressed air,
to avoid contamination.He has made the plans and all parts, except the
screws.The engine is not for sale.
Centaurus Engine Run
First test bed run of the RNHF Centaurus engine after it has been
overhauled Aug 11.
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".
Starting Three Old Aeroplanes
In a time before health and safety was invented, aeroplanes were started by
hand. Watch the man jump back as he lets go of the propellors. Sadly, they
were unable to get the Bleriot to start and run properly.
Videoed at Brooklands.
