Can we please discuss the Bristol Blenheim flight model?
« on: August 15, 2013, 09:32:49 AM »

I am re-reading Donald Caldwell's JG26 Top Guns of the Luftwaffe and it seems to me what was depicted in this book doesn't mimic what we see in IL-2 these loops, power climbs, barrel rollers and extreme G's with the wings not ripping off are uncharacteristic of the lumbering under powered Blenheim Mk I, and if I may add the weight of fire from the Blenheim Mk I seems isn't accurate for its armament - which were never used as fighter bombers like the Bf 110.

Blenheim Mk I
Power/mass: 0.13 hp/lb (.21 kW/kg)
Rate of climb: 1,500 ft/min
Armament:  1 × .303 in (7.7 mm) Browning machine gun in port wing
                  1 × .303 in (7.7 mm) Browning guns in rear-firing under-nose blister or Nash & Thomson FN.54 turret


Messerschmitt Bf 110 C-4
Power/mass: 0.3644 kW/kg (0.155 hp/lb)
Rate of climb: 2,500 ft/min
Armament: 2 × 20 mm MG FF/M cannons (180 rpg - 3 drums with 60 rpg, cannon were reloaded by rear gunner or radio operator during flight)
                 4 × 7.92 mm (.312 in) MG 17 machine guns (1,000 rpg)
                 1 × 7.92 mm (.312 in) MG 15 machine guns for defense

Three-seat twin-engined light bomber, powered by two 840 hp (630 kW) Bristol Mercury VIII radial piston engines, and a turret can some how cork screw with 9,790 lb empty seems a tad absurd.

The Blenheim Mk I behaves more like a fighter than a bomber. Isn't there anyway this can be corrected?

Welcome X-Man.
That you for your viewpoint on this fine classic aircraft, it was great in so many
ways and it also had its flaws like so many other planes from its time.

This IL2-1946 is but a "game", it will NEVER duplicate the real airplanes in flight or behaviour to
a 100% reality.
It may come close to imitating these classic WW2 airplanes or some of the WW1 and Jet-era aircraft, but never to a 100%. It is a "game".

Are you sure you're quoting data for the correct version?

(In fact, i know exactly where you found it. And the data is NOT for Mk. I.)

The chin guns existed only on Mk. IV, which was quite different than Mk. I - much heavier, somewhat bigger, up-armored, carried extra guns and fuel... so despite stronger engines it actually had marginally weaker performance.

Of course, the standard Mk. I should be nowhere near Bf 100 in real life - apples and oranges - but there also was a Mk. IF, which was intended as a long range escort fighter, and carried a 4 x .303 machine gun belly pack, crew of two. And a modded version of this is in DBW.

So, maybe it's this fighter version what is giving you trouble?
