LTV XC-142 Tiltwing aircraft. . The Ling-Temco-Vought (LTV) XC-142 was a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. . The Ling-Temco-Vought (LTV) XC-142 was a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. An XC-142A first flew conventionally on 29 September 1964, and on 11 January 1965, it completed its first transitional flight by taking off vertically, changing to forward flight and finally landing vertically. Its service sponsors pulled out of the program one by one, and it eventually ended due to a lack of interest after demonstrating its capabilities successfully. From Wikipedia., the free encyclopedia My fascination for the experimental V/STOL aircraft XC-142 has always been huge. I think I saw it for the first time in a French Sci-fi comic album in my teenage years. Even though it never left the prototype stage, I think it was a very important stage towards the Bell XV-15 and the later Bell/Boeing V-22 Osprey. Here the sideentrace is opened. It is hinged on a double linkage to allow the 3 plate thick door to be pulled out before it swings open. I started designing this model in September 2018, and initially I had no plans for adding any functional features, except that at least the wing should be able to tilt like the real aircraft. When I realized how big it would be, I thought there would be room enough for an electric motor inside the fuselage which could drive the propellers through axles and gears. Here the side of the cockpit is removed to show you that the model contains a cockpit interior with instruments and steering column for the two pilots. On the real plane all engines are interconnected through axles and gears, so that the loss of power on a single engine wouldn`t be catastrophic. It also synchronizes the propellers so that each propeller on the same wing-side is offset 45 degrees to each other. All of this, I tried to replicate with my model, and spent way too much time designing it, just to realize that because of a flaw in the LDD designer program, some of the gears had way too much friction to let the propellers spin freely. Had I known of the troubles with the propeller drive, I guess I wouldn`t have spent so much time tinkering with the landing-gear and wing tilt mechanism, because these also had to be modified to work better. And even after modification they don`t work perfect. Lesson learned: If you`re planning to make Technic functions, make real tests with real parts, not with LDD! One thing however works OK, The cargo ramp! The cargo ramp open in more sections, the cargo ramp for loading goods inside the plane, and the upper doors folding under the tail rudder. The wedge-piece covers the gap under tail when the cargo doors are closed. A direct front šview showing the anhedral angle of the main wings. The model is quite heavy, weighing almost 1,3 kilograms. Getting a little tired of redesigning, I decided to just stop here and present my model as it is. So the wing still contains most of the axles and gears, (some of it visible on the underside) but unfortunately none of it is functional. Nothing is so bad that it isn`t good for something else. Letting go of the propeller drive I could change the propellers for a more accurate looking one with a small pitch to the blades. More pictures on my Flickr Hope you enjoy the pictures.
