Strategic Planning & Schedule
The overall strategic project objectives of the Smart Fixed Wing Aircraft –ITD are unchanged since the principle definition at the project operational start in the summer of year 2008.
As expected, a robust planning and scheduling of the program emerged gradually along the major stages implementing CleanSky, namely releasing the proposal, operationally launching the project with the partners when receiving the project grant, and with the full implementation of the program when the CleanSky Joint Undertaking became autonomous.
A particular milestone towards a robust detailed technical planning of SFWA was the selection of the demonstrator vehicles for the smart wing and the CROR engine in April 2009, including the start of the related bottom up planning.
For the maturing of the smart wing, a parallel development of passive and active flow and load control technologies is a key part of the plan, with clear target to flight test a large size smart wing based on the concept of natural laminarity, possibly to be followed by a second, even more advanced hybrid “active” flow control laminar wing demonstrator. In this context it is important to understand that even the “passive” natural laminar wing does well include a number of active flow and load control technologies.
After the principle decision for a flight test demonstration of the large smart wing article on board the Airbus A340-300 test aircraft was taken in April 2009, it became clear that a second phase active laminar wing flight test demonstration, in size and profile similar to the natural laminar wing, is beyond the scope of time and budget available in SFWA.
The detailed planning for the high speed smart wing demonstration flight tests conducted until February 2010 revealed the complexity and volume of this task, leading to a technology roadmap with the start of the flight tests rescheduled to the third quarter of 2014.
The ground and flight demonstration schedule for smart wing low speed technologies remains almost unchanged since the initial setup of the overall project timeline. Flight tests are planned to start in the second quarter of 2013.
The principle decision for a full size CROR engine demonstration flight test in SFWA was taken at the end of 2008, with flight tests envisaged to start at the end of 2012, but without any detailed review of the demonstrator options being available. It is important to note that in the case of the CROR engine FTB, the planning toward the testing in the SFWA-ITD and SAGE-ITD depend on each other and require a close harmonization. In the course of the detailed feasibility study for the advanced CROR concept, and the selection of the Airbus A340-600 as flight test vehicle, the start of the flight tests was scheduled for the end of 2015, to provide the time required to prepare the engine and the integration to the demonstrator.
This planning was made in close alignment with the engine manufacturers in SAGE. It is important to note that key targets in the SFWA-ITD remain unchanged. The schedule, inparticular for the two major demonstration flight tests with the smart wing and the CROR
engine, was reviewed as a result of a detailed analysis and planning following the choice of the test vehicle, and to be coherent with the R&T strategy of Airbus and the contribution industry partners.
To complement the activities to develop, integrate and demonstrate the technologies in SFWA, paper “aircraft concept” studies were added to the plan, in order to be able to assess the value and consequences of the SFWA-ITD technologies at overall aircraft level in a timely coherent manner. The SFWA-ITD consortium is fully committed to the actual technical planning and to prepare, conduct and exploit the flight demonstrations within the lifetime of CleanSky.
