At the time this was the worlds only Subaru on an RV9A using a hydraulic constant speed prop. This prototype unit has all of the same features of the original Geared Drives PSRU including its own oil reservoir, oil pump and filtration system, drive port for hydraulic prop governor, and flywheel and centrifugal clutch assembly. This airplane with the P2 prototype Geared Drives PSRU can be seen at Sun n Fun Air Show, Lakeland, FL, April 21-26, 2009. Look for the Geared Drives booth N52 for directions the aircraft location.
Eggenfellner Subaru First Start
First start of my Eggenfellner Subaru E-6 engine. This is a converted
automobile engine for aircraft use and is capable of producing 200 hp.
Instead of burning just expensive aviation fuel, I will be able to use the
cheaper 92 Octane auto fuel, or as necessary, aviation gas. Repairs and
maintenance of this engine will also be cheaper then a typical aircraft
engine. Being water cooled, it will have far less vibration and will be
quieter then the typical air cooled aircraft engine. It will eventually be
attached to my RV-8A that I am currently building.

TNT Boeing 737-300F Accident at Birmingham
Investigators have disclosed that the TNT Airways Boeing 737-300 freighter
which conducted an apparent gear-up landing at Birmingham Airport, UK last
month had actually lost its right main undercarriage during a failed
attempt to land at Nottingham a few minutes earlier.
Owing to poor weather at London Stansted, following a flight from Liege,
Belgium on 15 June, the aircraft had diverted to Nottingham East Midlands
Airport and was carrying out a Category IIIA approach to runway 27 at
around 05:40, reports the UK Air Accidents Investigation Branch (AAIB).
About 1nm (1.8km) from touchdown the aircrafts approach became unstable,
after a momentary disconnection and re-engagement of the autopilot. The 737
rose above the glideslope, before descending rapidly and deviating to the
left of the centreline.
Although the crew began a go-around the aircraft landed heavily on grass to
the left of the runway threshold the impact tearing off the right main
landing-gear and causing damage to the right inboard flaps, wing-fuselage
fairing, hydraulic system and the rear freight hold door.
Despite the damage, and although the aircrafts outer wing and starboard
engine contacted the ground, the 737 managed to become airborne again. The
crew declared an emergency and diverted to Birmingham, where weather
conditions were good, touching down on runway 33 at 06:02.
With its right main-gear absent, the aircraft came to rest on its starboard
engine. Neither of the two crew members of the 737-300, a 19-year old
example registered OO-TND, was injured.
Both airports suffered disruption to operations as a result of the
accident. AAIB personnel are carrying out an inquiry into the
circumstances. The organisation says: At this early stage of the
investigation it is not considered necessary to make any formal safety
Geared Drives 200Z PSRU for Subaru
Test running the Geared Drives PSRU for Subaru on our test engine mule,
Frankenstein. Running for eight hours this day, the oil temperature is
cool enough you can wrap your hand around the oil filter and it is barely
over body temperature. Swinging a 72" Hartzell two blade hydraulic prop at
full pitch, the gearbox is performing perfectly and ready to take its place
as a retrofit to Eggenfellners gearbox. Torsional harmonics are resolved
via the Geared Drives centrifugal clutch system.
Gipson's RV-10 with Geared Drives LS1 Engine Runup
Bill Gipson of Conroe, TX runs his RV-10 with the Geared Drives PSRU and
LS1 Firewall Forward Package built by Bud Warren. Notice that the engine
runs great at any RPM. We are expecting fuel burn rates from this
combination in the range of 7-15 GPH. With torque multplication throught
the Geared Drives PSRU the performance will be astounding! Be sure and
notice that there is no gear noise at all heard with this redrive, just the
smooth throaty sound of a Corvette engine.
Antonov An-225 Mriya Tour - Zagreb Airport ZAG/LDZA Full HD
It's a beautiful Saturday (9.11.2013.) morning and it's the best time to
take a bus tour of the largest plane on Earth, The An-225 Mriya :)
Also, I would like to give a huge thank you to the driver of the tour bus
for a awesome ride close to the aircraft and a huge thank you to the staff
of Zagreb Airport for giving us spotters this chance to film this
magnificent aircraft close-up.

The British Aircraft Corporation TSR-2 - Excellent Documentary
"All modern aircraft have four dimensions: span, length, height and
politics. TSR-2 simply got the first three right."— Sir Sydney Camm.
The British Aircraft Corporation TSR-2 was a cancelled Cold War strike and
reconnaissance aircraft developed by the British Aircraft Corporation (BAC)
for the Royal Air Force (RAF) in the late 1950s and early 1960s. The TSR-2
was designed to penetrate a well-defended forward battle area at low
altitudes and very high speeds, and then attack high-value targets in the
rear with nuclear or conventional weapons. Another aspect of its combat
role was to provide high-altitude, high-speed photo reconnaissance,
requirements that necessitated incorporating "state-of-the-art" aviation
technology that would make it the highest-performing aircraft in these
roles. Only one airframe flew and test flights and weight rise during
design indicated that the aircraft would be unable to meet its original
stringent design specifications. The design specifications had been reduced
as the results of flight testing became available.
Ravin 500 N913RA_0001.wmv
N913RA is a Ravin 500 kit from South Africa. I provided some assistance,
paint, and design for this aircraft from Jan 09 until it flew on July 22
2009. Its powered by a GM LS1 fuel injected V8, so i like to call it the
Ravin 500 Super Sport. I built a custom front cowling to fit the automotive
engine, and did many many hours of fiberglass work on this #2 Ravin in the
Western Hemisphere. This one is actually Kit #13 and is now one of the 20
or so flying Ravin aircraft all around the world.
RV 10 Run up with Geared Drives FWF engine package
Note: battery was a little low...Bill Gipson of Conroe, TX runs his engine
up, cycles the prop, and shuts it down for viewers. This was immediately
after taxiing around the airport and filling up with fuel. This airplane
runs cool, even on taxi. Note that the centrifugal clutch starts the prop
just after the engine starts and also that the prop spins to a stop upon
Geared Drives PSRU for Subaru Prototype Test Run
By popular demand, Bud Warren of Geared Drives has developed a new spur
gear and centrifugal clutch PSRU for Subaru! This double reduction redrive,
accomodating reduction ratios up to 3:1, is exceeding all expectations in
testing. This unit, like the original, has its own oil pump, oil reservior
and filtration system, but best of all allows the use of a constant speed
prop (or any prop you wish) since it has a drive port for your prop
governor built right in. Oil temps run cool, the unit is absolutely quiet
and lighter in weight than the others. The unit mounts on a plate like
Eggs. As seen here it is mounted onto a 350 Chevrolet engine (Frankenstein)
and original Geared Drives back cover just as a transition to the Chevy for
test running only. See our website for more information.
Aircraft Emergency And Landing in a Glasair - the impossible turn ???
My Glasair engine is a Subaru SVX EG-33. Six bearings in the planetary
speed reduction unit failed during departure. I declared an in-flight
emergency and immediately returned for landing. Total flight time was 63
I failed to plug the camera mike in so you don't hear the engine monitor
blaring out alarms or chatter between other pilots and myself.
Departure was made with 10 degrees of flaps and remained there until
landing with 25 degrees. The buzzer during much of the flight is the "gear
up" with "flaps extended" warning horn ... the stall horn never sounded.
Speed did drop but the flight never reached critically low speed. Power
was intentionally reduced to keep gearbox temps down. I fly patrol flights
at 500 ft or less, often 6 to 7 hrs a day. So I do have low level
maneuvering experience. Some may call this the impossible turn but power
was available during the entire flight.
