Alisport Silent IN

[ANON]

Greetings,

I was wondering if anyone in the states has any experience with
this A/C? The "Alisport Silent IN"

http://www.alisport.com/Default.htm

Actual build times, engine reliability and TBO, problems involving the
sinlge blade prop
re' nonsymetric forces as a byproduct of thrust, etc.......

Thanks

Dear Anonymous,

I feel compelled to reply since you are not likely to get any owner
feedback, unless from someone in Europe.

A bit of background information first: Alisport has displayed the
Silent-IN aircraft for the past few years at both Oshkosh and Sun n'
Fun to establish an initial prescence in the US. I travelled to Europe
in September of this year to visit the factory, meet with the owners,
designers, engineers, test pilots, and technicians. Additionally, I
met with the German designer of the electric self-launch Silent-AE1.
In brief, I was impressed with the Alisport operation & the flying
qualities of the Silent and negotiated to be the US representative for
Alisport. There are presently over 35 Silents flying in Europe and I
am pleased to report that the first US sale of a Silent-IN quick-build
kit was to a builder in California last week.

Now, to answer your questions: In late September, I took delivery of
the demonstrator Silent-IN from our logistics center in Baltimore, MD
and moved it to my location at the Tullahoma Regional Airport in
Tennessee. It is the only Silent presently flying in the US and it is
a delight to fly.

The kits are advanced quick-builds and the factory estimates 350 hours
for construction of the Silent and an additional 150 to complete the
Silent-IN. Note that a standard Silent can be upgraded to the
self-launch Silent-IN at a later date. We will post the actual build
time for the kit in California when the numbers become available.

I am constantly impressed with the engine. It has mapped electronic
fuel injection and electronic ignition. The ECU receives inputs from
pressure and temperature sensors and adjusts the mixture accordingly.
It has electric start and a counterbalance shaft. The ease of starting
is exceptional for a two-stroke. The factory recommends a TBO of 300
hours. This may appear low when compared with traditional aircraft
engines, but this equates to 3600 5-minute launches (at 100 flights
per year it would take 36 years to reach TBO).

The single blade propeller is a teetering unit and therefore places no
bending load on the propeller shaft. The offset counterweight balances
the thrust load of the propeller. The entire system has undergone
rigorous testing to ensure that the engine/propeller combination
performs as intended. The testing included a complete frequency
analysis using accelerometers. Additionally, the patented propeller
arrangement was the subject of a very interesting article in Technical
Soaring in which both the theoretical and experimental analyses were
presented.

I trust that these responses answer your questions. If you would like
further information feel free to contact me directly via e-mail at

Best regards and happy soaring,
