Best Climber? Yak 1 Vs Bf109F-2

Best Climber? Yak 1 Vs Bf109F-2

Which plane climbs best?

I thought the Bf109 could climb better than the Yak. Turns out thats not the case, at least not for the F-2.

(At 46:43)

Bf 109 F-2

Maximum true air speed at 5000 m, engine mode – Emergency: 606 km/h

Climb rate at sea level: 16.4 m/s

Climb rate at 3000 m: 14.1 m/s

Climb rate at 6000 m:

10 m/s

Dive speed limit: 850 km/h

Maximum true air speed at sea level, engine mode – Emergency: 528 km/h

Maximum true air speed at 2000 m, engine mode – Emergency: 563 km/h

Maximum true air speed at 5000 m, engine mode – Emergency: 606 km/h

Yak-1 series 69

Maximum true air speed at 4000 m, engine mode – Nominal, 2700 RPM: 582 km/h

Climb rate at sea level: 16.9 m/s

Climb rate at 3000 m: 15.0 m/s

Climb rate at 6000 m:

9.4 m/s

Dive speed limit: 720 km/h

Maximum true air speed at sea level, engine mode – Nominal, 2550 RPM: 514 km/h

Maximum true air speed at 2000 m, engine mode – Nominal, 2700 RPM: 549 km/h

Maximum true air speed at 4000 m, engine mode – Nominal, 2700 RPM: 582 km/h

Conclusion:

The Bf109F-2 is not a better climber than the Yak 1. The strength the F-2 DOES have is much better dive speed.

The F-2 also turn fights better than later 109s except not as well as the earlier E-7.

The ailerons will come off a Yak 1 above is max dive speed, so if you are in a F-2 and chased by a Yak, best thing you can do is dive faster and get distance. After a few minutes above 720kmh you will be far away.

What about the climb of the Bf 109 F-4?

Maximum true air speed at 6000 m, engine mode – Combat: 635 km/h

Dive speed limit: 850 km/h

Climb rate at sea level: 19.5 m/s

Climb rate at 3000 m: 18.8 m/s

Climb rate at 6000 m:

14.9 m/s

Its actually 4 to 5 meters pers second faster than a Yak 1 (at higher altitudes that is…).

What about the Bf 109 G-2?

Maximum true air speed at 7000 m, engine mode – Combat: 656 km/h

Dive speed limit: 850 km/h

Climb rate at sea level: 21.0 m/s

Climb rate at 3000 m: 19.5 m/s

Climb rate at 6000 m:

16.5 m/s

Ok I see a pattern here: Both the Yak 1 and the F-2 climb speeds and max level speeds drop at higher altitudes, . But the F-4 and G-2 maintain their climb speeds at altitude (& their level speeds too).

Bf 109 G-4?

Maximum true air speed at 7000 m, engine mode – Combat: 640 km/h

Dive speed limit: 850 km/h

Climb rate at sea level: 20.1 m/s

Climb rate at 3000 m: 18.9 m/s

Climb rate at 6000 m:

15.4 m/s

So what about the stronger Yak – The Yak-1(b) series 127?

Dive speed limit: 720 km/h

Maximum true air speed at 4500 m, engine mode – Nominal, 2700 RPM: 600 km/h

Climb rate at sea level: 17.0 m/s

Climb rate at 3000 m: 15.0 m/s

Climb rate at 6000 m:

9.5 m/s

Conclusion:

The Bf109F-4, G-2 and G-4 all out climb the Yak 1 and Yak 1b at higher altitudes. BUT the Bf109F-2 can not.

And finally what about the Bf109E-7?

Dive speed limit: 850 km/h

Climb rate at sea level: 14 m/s

Climb rate at 3000 m: 13.3 m/s

Climb rate at 6000 m:

7 m/s

It is slower in climb and in straight line max speed than both those Yaks, but it turn fights so well and it retains that Bf109 characteristic of 850Kmh max dive speed. So it can turn fight very well and it can also dive faster than Yak 1, 1b.

Conclusion:

One can infer from the data above that the Bf109 (except E-7 and F-2), is much faster max straight line speed than Yak 1, 1b at higher altitudes.

The Bf109 dive speed is 130kmh faster than a Yak (850 km/h versus 720 km/h) and its climb is faster at high altitudes (except the F-2 which is the same as Yaks, and E-7 which is slower than Yaks). BUT stronger climb alone is not different enough than a Yak to be a decisive factor. If you are in a 109 trying to out climb a Yak at high alts you can do it but it will cost you some 95% power. You risk breaking your engine after a few of these climbs. Bf109 would be strongest in a higher altitude boom zoom role while incorporating both higher dive speed than Yak and strong climb in one maneuver. For example being at 5000m and diving on Yaks at the cloud base at say 3000m and zooming back up again.

A plane in the jungle!

A plane in the jungle!

Apparently a WW2 Japanese heavy. What could it be? How exotic! I would like to do an expedition to see this plane. It is in a remote area, however I see on Google Earth there is a airstrip not far from there. I imagine it has already been inspected before.

I cant yet figure out which one it is. Could it be this one?

I dont think so, because the wing of the crashed plane is very straight, where as this one has a swept leading edge.

It could be a Betty but with the engines removed
