Hello Paul,

   have not found very much.

   Starting in 1987 a team with Brian Crighton has built the RC 588
   first start in Darley Moor  driver Malcolm Heath  third place

   Until 1992 the team was sponsored by John Player
   Driver  Ron Haslam + Robert Dunlop

   In 1992 Steve Hislop has won the Senior TT on the Isle of Man with a
   NRS 588, supported by a private team with B. Crighton + Colin Seeley

   1992 was also the year of the management buyout for UAV engines
   first "Alvis", than "UEL" (UAV Engines Limited) ...

   Perhaps some one out there has more facts + data ... Would be nice
   to read / see more details ...

   The early Norton motorbikes have tended to produce a lot of smoke
   when started after a longer stop. Although the amount of oil they
   used was very small, the lubricant has found its way past the side +
   corner seals into the combustion chamber ... - pretty embarrassing
   for an otherwise modern bike ...

   So I have a little bit of fear, that your oil squirter technology
   could act the same way - some kind of oil seals would be recommended
   ... ?

   Thanks for the C-W pictures - just the right stuff for a "technology
     romantic" like me ... ;-)

   All the best to your TTC project

   Frank Herfert.



   "Brian Crighton the brains behind the Norton rotary racers was no
   stranger to racing himself having been British 50cc champion in 1973, 74
   and 76 on a self prepared highly modified 4 stroke Honda. During this
   time Brian also ran a Honda dealership he had set up near his Midlands home.

   After selling the dealership in 1986 Brian’s engineering talents came to
   the attention of the Norton factory in Lichfield and he joined the
   company working in the service department.

   Within 12 months of joining Norton Brian Crighton was promoted to the
   Research and Development department where he was involved in the
   development of the Norton rotary engine.  With his expertise in
   engineering Brian quickly became convinced that the rotary engined road
   bike currently being used by the Police would make a great base for
   developing a race bike."

   I don't think they won the Isle of Mann in those days.

   I think some of those Norton engineers went to work for Austro Engines.
   Richard Negus may have been one.

   Thanks for all the tech papers. Have not had the time to read them all.

   Frank,

   A few corrections worthy of note.

   Steve Hislop won the TT but JPS was reluctant to sponsor the TT due to
   dangers, the team was Run by Barry Symons, and was the same JPS Norton
   team re badges just for the 1992 TT,
     B.Cighton+ Colin Seeley, ran a totally separate team sponsored by
   Duckhams Oil the following year?.
   The smoking that you speak of was due oil build up within  the plenum
   chamber ( the frame ) poor pickup of the a pipe linked to the air intake
   when this got blocked and the result was a build up of oil in the hollow
   box frame that also acted as the pre-carb air box silencer, the air
   intake sucked cooling air first through the engine, into the air box and
   then into the carbs, so oil would build up within the frame.

   The race bikes were fitted with Exhaust Ejectors, this was based on test
   carried out with Teledyne Continental Motors ( TCM) in 1996

   The Race bike also used RAM air to push air into the motor at High
   speed, we clocked 194 mph at the Northwest 200.

   ex  Test rider for BSA NVT  1968 to 1971, Chief Test rider and
   Manufacturing Director at Norton Motors Ltd (78) ltd, ending in 1993, EX
   interim race team manager for JPS Norton for later part of 1989

   So Midwest added the rotor cooling blower?

   What do you think of the rotor cooling oil squirter idea?

   Do you know Richard Negus?

   Do you know Emon Hurley? Is he still alive?

Paul,

My friend Wayne Tolson, who incidentally owns one of the genuine factory Rotary JPS Norton race bikes, corrected me on the dates of the work done on the TCM Ejector and the Duckham 1992 team date, sorry.

Correction on my correction, the TCM Exhaust Extractor work was carried out 1986, we also did work for Mercury Marine, for the late "Dr Benjamin Sheaffer" Ben

The Duckhams team was in 1992

http://www.nortonmotors.co.uk/Rotary%20Racing.htm


We had blowers under test bed and on the race machines, Electric Blower and belt drive.

So Midwest added the rotor cooling blower? do not know this, /but could have been my date error made you think this./

What do you think of the rotor cooling oil squirter idea/?,have lost the link when I looked on my mobile, do you have the thread to this idea?
/
Do you know Richard Negus? Yes,/I see Richards a couple of times a year/

Do you know Emon Hurley? Is he still alive? /Sorry did not know him.

So it sounds like Norton developed the rotor cooling blower.

As I understand it, the Norton engine was manufactured by Midwest
for awhile and certified as an aircraft engine. That cast the design in concrete'.

They in turn were bought by Austro engines AKA Diamond Aircraft.

The rotor cooling  blower was part of the design. It results in a 10 to
15% fuel consumption penalty over the Mazda oil cooled rotor. It is less
efficient to cool with pumped air than pumped liquid according
to Kays & London.

Some work on diffusers (called headers in this book). Very comprehensive.
