WWII Messerschmitt Bf 109E Fighter Free Aircraft Paper Model DownloadThis aircraft paper model is a Messerschmitt BF 109E (aka E), a variant of the German World War II fighter aircraft Messerschmitt BF 109, which was designed by Willy Messerschmitt and Robert Lusser during the early to mid-1930s, the paper model is shared by Jibo.

In late 1938, the Bf 109E entered production. To improve on the performance afforded by the 441–515 kW (600–700 PS) Jumo 210, the larger, longer Daimler-Benz DB 601A engine was used, yielding an extra 223 kW (300 PS) at the cost of an additional 181 kg (400 lb). A much bigger cooling area was needed to disperse the extra heat generated by the DB 601 and this led to the first major redesign of the basic airframe. Enlarging the existing nose mounted radiator sufficiently to cool the engine would have created extra weight and drag, negating some of the performance gains afforded by the increased power, so it was decided to move the main radiators to the wings, leaving the oil cooler under the nose in a small, streamlined duct.

The new radiator position also had the effect of counterbalancing the extra weight and length of the DB 601, which drove a heavier three-bladed VDM propeller. To incorporate the new radiators the wings were almost completely redesigned and reinforced, with several inboard ribs behind the spar being cut down to make room for the radiator ducting. Because the radiators were now mounted near the trailing edge of the wing, coinciding with the increased speed of the airflow accelerating around the wing's camber, the overall cooling installation was more efficient than that of the Jumo engined 109s, albeit at the cost of extra ducting and piping, which could be vulnerable to battle damage. In addition the lowered undercarriage could throw up mud and debris on wet airfields, potentially clogging the radiators.

To test the new 1,100 PS (1,085 hp, 809 kW) DB601A engine, two more prototypes (V14 and V15) were built, each differing in their armament. While the V14 was armed with two 7.92 mm (.312 in) MG 17s above the engine and one 20 mm MG FF in each wing, the V15 was fitted with the two MG 17s mounted above the engine only. After test fights the V14 was considered more promising and a pre-production batch of 10 E-0 was ordered. Batches of both E-1 and E-3 variants were shipped to Spain for evaluation, and first saw combat during the final phases of the Spanish Civil War. [Source: wikipedia]
