This is an ambitious model for relatively experienced modellers.
The painted example was my prototype. I have since refined the undercarriage parts greatly improving their shape, the presently unpainted example shows the fit and improved appearance of the new parts.
It is supplied as STL files at 1:72 with and without support. I successfully printed all parts on a Halot Mage Pro using Creality fast resin and Dynax mode. You may consider using your own support choices to suit your printer and resin choices.
Assembly:
Join the two front halves of the fuselage (which include wings and engines).Add the rear fuselage including rudder and tailplane.Add two fron wheels and then the pair of right and left main wheels.Add sufficient weight inside the front section to ensure it balances properly.TAKE CARE the undercarriage is to scale and therefore a bit fragile.Paint the cockpit interior and fit inside the front of the fuselage.Add two pilots, I suggest either two smaller pilots on one small and one large.Print the canopy and domes in clear resin and fit.Fit the optional RATO units underneath each engine, if desired. The front of each unit should be 10mm back from the front of the jet intake.
If you don't have clear resin, you can print the main canopy as a bare frame, this could be lined with clear plastic heat formed around a suitable former. Domes are best made by heat forming sheet plastic around the end of a small paintbrush.
The Development and Legacy of the Junkers 287A Groundbreaking Experiment in AviationThe Origins of Junkers 287The Junkers 287 was an ambitious project born out of the desperate circumstances of World War II. As the war progressed, the Luftwaffe sought new technologies to gain an edge over the Allies. The idea for the Junkers 287 was conceived in 1942 by Dr. Hans Wocke, an aeronautical engineer with a keen interest in unconventional aircraft designs. The goal was to create a bomber with unparalleled performance capabilities, capable of reaching high speeds and altitudes while carrying a significant payload.Design and DevelopmentWhat made the Junkers 287 unique was its forward-swept wing design, a radical departure from conventional aircraft of the time. This design aimed to improve aerodynamic efficiency and manoeuvrability at high speeds. The forward-swept wings reduced drag and enhanced lift, promising better performance than traditional wing configurations. The aircraft also featured four jet engines mounted in pairs under the wings, a novel arrangement that aimed to optimize thrust and stability.During the development process, several prototypes were built, with the first, known as the Ju 287 V1, taking shape in 1943. The construction of the V1 prototype was a mixture of components from other aircraft, including the fuselage of a Heinkel He 177 and the tail section of a Junkers Ju 388.First Test FlightsThe Junkers 287's maiden flight took place on 16 August 1944. Piloted by Flugkapitän Siegfried Holzbauer, the aircraft demonstrated promising performance characteristics. The forward-swept wing design proved effective, providing stable flight and impressive agility. However, the test flights also revealed several challenges, including structural issues and engine reliability problems. Despite these setbacks, the engineers were optimistic about the aircraft's potential.Subsequent test flights continued into early 1945, with modifications and improvements made to address the initial issues. Unfortunately, the deteriorating war situation and dwindling resources hindered further development. The advancing Allied forces meant that the Luftwaffe's priorities shifted, and experimental projects like the Junkers 287 faced increasing difficulties in securing funding and materials.The Fate of the Junkers 287 Post-WarAs World War II came to an end in May 1945, the development of the Junkers 287 was abruptly halted. The Allies captured the remaining prototypes and documentation, marking the end of the project. The forward-swept wing design, however, did not go unnoticed. The Soviet Union, in particular, showed keen interest in the innovative concept.In the post-war years, the Soviets took custody of some of the Ju 287 prototypes and employed several German engineers, including Dr. Hans Wocke, to continue research and development. This led to the creation of the OKB-1 EF 140, which incorporated many design elements of the Junkers 287. While the EF 140 did not enter mass production, it played a significant role in advancing Soviet jet aircraft technology.In the West, the innovative forward-swept wing design of the Junkers 287 influenced future aviation developments as well. It laid the groundwork for experimental aircraft like the Grumman X-29, which successfully demonstrated the advantages of forward-swept wings many decades later.LegacyThe Junkers 287 remains a symbol of ingenuity and ambition in aviation history. While it never saw active service or mass production, its design and the lessons learned from its development had a lasting impact on both Eastern and Western aviation advancements. The aircraft's unique forward-swept wing design continues to be a subject of interest and study, highlighting the innovative spirit that drove its creation.In conclusion, the Junkers 287 was a remarkable achievement in aviation during a tumultuous period. Its development story is a testament to the challenges and triumphs of pushing the boundaries of engineering and design, leaving a legacy that transcended the immediate aftermath of World War II.
