Just curious as to why the time to climb is always done from ground level to 10000 feet. We all know Rare Bear owns this record, but what if the climb was done from 20000 to 30000 feet...I would think a P-51 would do better in this contest as it performs much better at high altitudes than does the Bearcat...

Re: Time to climb
Let the debate begin! As stated RARE BEAR owns the record for 0-10,000 ft. Also suggested, that the Mustang would probably fare better than the Bearcat from 20,000-30,000. dunno, are we talkin' stockers? Everybody knows RARE Bear is FAR from stock. So.....Strega vs. Rare Bear to 10,000? Strega vs Rare Bear 20,000-30,000 ft? That I/WE would love to see.
I read an old Air Classics article regarding post-big one testing of combatants and it said from 0-10,000 was shared by the Hawker Tempest and Spitfire XIV with a BF-109G second and the Mustang third. Granted, these are all stockers and (for all I know) pre-Bearcat.
Someone mentioned "drag racing": maybe a contest for Rare Bear/Strega/323 to 10,000? What say you? Wouldn't THAT be cool.Last edited by V1670; 08-23-2013, 10:54 AM.

Re: Time to climb
OK, I think 20k to 30k is a silly metric since its already been stated that the higher starting speed probably determines the outcome.
But running with it anyway and say you somehow guarantee an agreed starting speed at 20k feet... Stock to stock, I'd SWAG that the Mustang probably wins because of its 2-stage two speed supercharger that was better than just about anything else without a turbocharger. Better wing, too.
Race Mustang? Depends on whether the high blower speed is disabled or not. Aren't most of the "tube" motors built without the high speed hardware? I seem to recall that Dreadnought's 4360 only has low speed blower for more strength in the gear train at high RPM / low altitude, but I've honestly forgotten about the Merlins. I'd bet that a stocker would beat most of the racers, they're just not built for that task.

Re: Time to climb
What prompted this question was an artical in an Air Progress magazine (July '73 issue which I still have) that had a mock dogfight between a Mustang and a Bearcat. In the artical they stated that they were prohibited from going higher than 18000 feet because the Mustang had a marked edge in perfomance over the Bearcat at altitudes higher than 18000 feet. I have no doubt that any Mustang, regardless of how it's modified would not be able to compete with a Bearcat from sea level to 10000 feet...that's where the Bearcat excels, but above 18000, I believe the Mustang would be superior...

Re: Time to climb
FYI, in reviewing FAI Records, it appears that Lyle Shelton's records have been "retired by changes of the sporting code" (see below for retired record information).
C-1 Speed over a 3 km course, 850.24 km/h 1989-08-21 Lyle Shelton (USA), ratified - retired by changes of the sporting code - 8437
C-1 Time to climb to a height of 3 000 m, 1 min 32 sec 1972-02-06 Lyle Shelton (USA), ratified - retired by changes of the sporting code - 8114
Even with the FAI not recognizing these records anymore, I feel that fans of Aviation Records will still recognize the accomplishments of Lyle Shelton as the ultimate Aviation Records for internal combustion engine airplanes.
At this time the Time to Climb record to 3000m for C-1d is held by Will Whiteside (Steadfast) at 2 min 03 sec
This is for an propeller driven airplane with internal combustion engine.

Re: Time to climb
The record is measured that way because it has a real world application. Going from the ground to 10k is something that most every aircraft will do every time it flies (generalization, I know).
I can come up with 100 random things that certain aircraft will excel at and others will not. But every aircraft takes off from the ground and climbs to cruising altitude.

Re: Time to climb
This 'Blue Angels Bearcat' site gives the climb rate of a 'stocker' as 4570 ft/min.
This graph compares the climb rates of some contemporaries inc' P-51 [ B though, not H..].
Quickest climb rate being 'bout 1,000 ft/min quicker than the listed mil-spec F8F..

Originally posted by Matt Jackson View PostStock Bear Cat eats the ass off a Mustang in a climb at any altitude below 25,000. Don't care what the manufacturer claims. Mustang zoom climbs great after a head of steam, but doesn't hold a candle to a Bear Cat / Sea Fury period. Propeller planes have high rates of climb in thick cold air because the propeller is much more effective down low. A corsair with the big blower eats the ass of of most up high. So to climb ten thousand feet fast you start in the thickest air possible and let it rip. Lyle did that and Lyle owns the record. He did it with full length wings, 3350 with fast turning nose case skyraider prop End of story.
Gonna be a great year!Wayne Sagar
