Messerschmitt Me 410
From Wikipedia, the free encyclopedia
The Messerschmitt Me 410 Hornisse ("Hornet") was a German heavy fighter and Schnellbomber used by the Luftwaffe during World War II. Though essentially a straightforward modification of the Me 210, it was designated the Me 410 to avoid association with its notoriously flawed predecessor.
Design and development
Development of the Me 210 had been underway since 1939, but the aircraft proved extremely unstable and was never considered for full-scale production. Modifications to the layout produced the Me 210C and 210D, which proved somewhat superior. As studies progressed on the Me 210D, it was instead decided to introduce a "new" model, the Me 410.
The major change between the Me 210 and 410 was the introduction of the larger (at 44.5 litre, 2,715 in3 displacement) and more powerful Daimler-Benz DB 603A engines, which improved power to 1,750 PS (1,730 hp, 1,290 kW) compared to the 1,475 PS DB 605s used on the Me 210C. The engine performance increased the Me 410's maximum speed to 625 km/h (388 mph), greatly improved rate of climb, service ceiling, and most notably the cruise speed, which jumped to 579 km/h (360 mph). It also improved payload capability to the point where the aircraft could lift more war load than could fit into the bomb bay under the nose. To address this, shackles were added under the wings for four 50 kg (110 lb) bombs. The changes added an extra 680 kg (1,500 lb) to the Me 210 design, but the extra engine power more than made up for the difference.
The new version included a lengthened fuselage and new, automatic leading edge slats, both of which had been tested on Me 210s and were found to dramatically improve handling. The slats had originally been featured on the earliest Me 210 models, but had been removed on production models due to poor handling. When entering a sharp turn, the slats had a tendency to open, due in part to the turn causing a drop in air pressure at the leading edge of the wings, analogous to the low pressure activation the slats were designed for in a slow landing approach (this problem was first observed on the prototype Bf 109E), which added to the problems keeping the aircraft flying smoothly. However, when the problems with the general lateral instability were addressed, this was no longer a real problem. The wing panels of the earlier Me 210 had been designed with a planform geometry that placed the aerodynamic center in a rearwards direction in comparison to the earlier Bf 110, giving the outer sections of the wing's planform beyond each engine nacelle a slightly greater, 12.6º leading edge sweepback angle than the inner panels' 6.0º leading edge sweep angle. This resulted in unreasonable handling characteristics in flight for the original Me 210 design. The new Me 410's outer wing panels had their planform geometry revised to bring the aerodynamic center further forwards in comparison to the Me 210, thus making the leading edge sweepback of the outer panels identical to the inner wing panels with both having identical 5.5º sweepback angles, and improving in-flight handling.
Deliveries began in January 1943, two years later than the original plan had called for, and continued until September 1944, by which point a total of 1,160 of all versions had been produced by Messerschmitt Augsburg and Dornier München. When it arrived, it was liked by its crews, even though its improved performance was not enough to protect it from the swarms of high performance Allied fighters they faced.
