What could be the ultimate lap speed in RENO ?

Re: What could be the ultimate lap speed in RENO ?

I'm pretty darn sure that's calculated LAP SPEED, MPH

Re: What could be the ultimate lap speed in RENO ?

Whaaa?
Mean lap speed?
Or peak speed down the shute.. would have to pull it in a tad for the pylons.. surely?

[Idaho_cowpony]

Re: What could be the ultimate lap speed in RENO ?

Yes...LAP SPEED, as in the one that's published for Qualifying..

[J.A.W.]

Re: What could be the ultimate lap speed in RENO ?

I take it you mean..
..that although the maximum straight-away speed [Mike's ~530 mph] - is not technically feasible to
be maintained as an average speed around the turns.. it will appear as an 'official lap speed'?

Surely.. not?..

Re: What could be the ultimate lap speed in RENO ?

The aircraft is timed around the course. (home pylon, to home pylon, as previously mentioned) Last year RARA published the course size as 8.1034 (According to their 'Optimum path', the course is actually under 8 miles, measured pylon-to-pylon.

So for example, last year Strega qualified with a lap TIME of 59.137, which equaled 493.299mph

To figure that:
8.1034 x 3600 = 29172.24
29172.24 / 59.137 = 493.299mph

It's essentially the actual (average, if you will) lap speed of the aircraft.

So for 530mph, they would have to fly a lap at, or under 55.041 Seconds.

In other words, I believe what Mr. Nixon is saying, is that it's possible for #7 to shave 4 seconds off it's lap time. I would say that is VERY reasonable.

Consider this; that September Fury was running what was essentially a stock motor, at conservative settings (albeit slow prop), and was able to post race speeds in the 450's. She probably had another 40mph in her, and that would put a few of those laps well over 500 as well.

Impressive.. thanks for the explanation, Joseph..
& Certainly something to be gunning for..

Re: What could be the ultimate lap speed in RENO ?

& for Juke..

How 'bout this for a Reno Lap Record proposal?

Make a design submission to Red Bull & Porsche..

A 'Thunder' sized airframe powered by an H-24 [ Napier Sabre-style]..

& constructed from 4 sets of their 4 litre flat six race mills en-bloc?

Add boost & fuel..[420hp x 4 = ~1680hp in atmo form, add a bar & 1/2 boost or so.. ~3,000hp?..]

Crank the numbers.. goer.. or not?

[J.A.W.]

Re: What could be the ultimate lap speed in RENO ?

I mean.. if they could do this kind of thing 40 years ago..

Re: What could be the ultimate lap speed in RENO ?

Or, slot 8 of these en-bloc in a small airframe for 2,800/3,360hp..

Yes J.A.W. this engine will do...but put it in a plane like this here VT-AERO...really small and lite AC that would have power to weight ratio nearly 1.2 ( or better ).



Even if you blew one of the engines you could still return to the runway.

Re: What could be the ultimate lap speed in RENO ?

Since most of the line drawings show non piston-engine aircraft, you'd have to do some adaptation, Juke.

My question would be, 1 prop or 2?

& if 2, then what configuration?

A Macchi MC sea-plane inline tractor type powering twin contra props?

Or Dornier 335 push/pull-style?

Another try at the Pond Racer lay-out?

A BD-5-type pusher?

All would require trans-sonic control capability, obviously..

Yes JAW...it needs an all moving canard and 800-900-(1000) km/h justed transsonic foils and 2 x fans that may have even 5 blades each. Are those engines air cooled or liquid cooled...even air cooled could do ninely ( less complex ).

Two engines in pusher mode attached to the tail fuse like in A-10. 2-stroke engines are tight packed and thus very little drag. Composite stucture and simple retractable gear ( main gear ). All systems manually operated and mechanic ( no fly by wire ). Foil could be 6-7% thick with lotsa sweep. Genuiely fast set up..maybe supersonic in dive.

Re: What could be the ultimate lap speed in RENO ?

Liquid cooled is a must.. for high specific out-put,[& even Porsche has gone there now]..
..lower frontal area ,close cowling & choice of cooling duct location is - in fact - a bonus, too.

& Juke, most importantly..
..make sure your proposal presentation graphics have the sponsors product in proper placement..

[J.A.W.]

Re: What could be the ultimate lap speed in RENO ?

Juke, have you checked out the XF-84H 'Thunderschreech'?

Maybe.. you could look at a scaled down version.. with a hi-po recip' standing in for the turbo-shaft..

Right I have to look for a sponsor...anyone interested ?

Here is a close up of my fighters...VT is the one best suited to for conversion.
