In volume 8 of “Gente dell’Aria” by Giorgio Evangelisti published in 2012, there is a description of an italian trimotor called Caproni CDR-10, equipped with three Isotta Fraschini “Delta” RC.41. CDR stands for Caproni-De Bernardi-Rossi. The latter was the engineer Lelio Rossi, former Technical Director of SAI Ambrosini. The project is not dated but probably it has been developed during the WWII, after the departure of Rossi from SAI Ambrosini, despite as Evangelisti point out, there is no evidence that Rossi ever joined Caproni group, so he could have proposed this project to Caproni as “free-lance” engineer.
The aircraft , a fighter/bomber, had a twin-boom layout with a central nacelle. In front of each boom is placed the engine with its tractor propeller, while the central nacelle is equipped with a pusher engine.
The aircraft, had a crew of two, pilot and bomber/gunner, placed ahead of the engine.
No dimensional data are available, while in the description (prepared by eng. Rossi) for the performance it is claimed a maximum speed of 710 km/h, that is a bit exaggerated in my opinion, considering the low power developed by the “Delta” engines.
In the book there is a plan view and the front view of the aircraft, signed by Eng. Rossi, but no side view.
Evangelisti in his book states that this project evolved into a four-engined aircraft, with the fourth engine placed into the nose of the central nacelle.
Does anyone has further info about these two mysterious projects ?
