1. 3D design of all components (30.000Euro)
Throughout this stage, all the components will be redesigned: structural elements, wings, engine-propulsion elements, landing gear, empennage, controls etc using SOLIDWORKS software.
2. CFD Simulation (50.000Euro)
Before materialising, the airplane will be subject to computer simulations using professional, dedicated packages (Computational Fluid Dynamics –CFD). Various working regimes of the propulsion will be simulated including the engine (Clerget 4V 50HP 1909), but also the take-off behaviour and flight. At this stage, an estimate of the propulsion will be obtained, performance and efficiency of the wings, overall plane capabilities and an indication regarding take-off speed will be determined.
3. Structural Elements Manufacturing (70.000Euro)
At the end of this stage the fuselage, upper and lower wing, tail wing, the empennage (St. Andrew ’s cross shape), cowling, connecting elements, landing gear as well as the other components will be built. The original plane had most of its’ components made of wood and plywood, some structural reinforcements being made of steel. The technology to be used will be as similar as possible to the 1910 one.
4. Manufacturing the Propulsion System (90.000Euro)
The jet propulsion system represents the very essence of the Coanda 1910 plane. The principle, which was considered revolutionary at the time, delivers the necessary power to move the plane forward without using a propeller. The propulsion system will be completely rebuilt because none of the original components still exist. The propulsion system consists of a 50 HP Clerget 4V engine (1909), a multiplier and a “turbine” (ducted fan) in two build options, injectors and manifolds.
5. Manufacturing the Command and Control elements (30.000Euro)
This includes manufacturing the command and control components of the propulsion system, wing warping, landing gear, empennage and other mechanisms.
6. Propulsion system - Bench Testing (50.000Euro)
After manufacturing, the propulsion system will be bench tested to ascertain the performance and limitations. Maximum rpm, vibration, efficiency will be observed, taking readings for flow, force and consumption.
7. Assembling the plane (10.000Euro)
During this stage, all comprising elements will be put together and tested, without starting the engine.
8. Testing of the functional replica (20.000Euro)
The airplane will be tested on the runway to check the take-off speed. During this testing session actual flight is not envisaged to take place.
