First Annual Review
21/02/2006 · After one year that VITAL has been launched, the first VITAL Annual Review held in Derby on February 21st - 22nd, 2006
The objective of this meeting was to present the achievement reached during the first 12 months of the project as well as the detail work for the next 18 months. The Scientific Officer as the Chairman reviewer and three reviewers of the European Commission assessed and commented the presentations.
The final comments of the Review Team with the detailed remarks are expected latter. Meanwhile, the Review Team expressed their very positive impression on the excellence of the programme management and on the technical aspects shown during the meeting.
The activity along the first 12 months was mainly focused on the implementation of the infrastructure and tools related to the project management; and in parallel, on technical specification: design concept, test planning, material selection etc…
Even if a large part of the tests are scheduled later on programme (between 2006 to end 2008), some partial results had been already performed and presented during the meeting.

Main achievements reached during the first 12 months were presented on the 1st Annual Review to the European Commission on June, 2006:
- The specifications for 2 aircrafts were produced by AIRBUS-F for Long Range /Short Range. The initial performance specification for the 3 VITAL engine configurations for both aircrafts was completed.
- For the Lightweight Fan design study, some materials were selected, and some specimens already manufactured like blade & casing material, and blade concepts and structural OGV started.
The specifications for tests have been carried out (Spin, Ballistic and fatigue tests), and some modification of the test facilities has already been implemented. The advanced instrumentation systems have been commissioned. And finely, the ballistic testing on specimens has already started.
- Aerodynamic & noise design of the blades and vanes for the DDTF Fan Rig started. The Preliminary Design review showed good progress towards the objective of high efficiency and low noise. The detailed design for blading and rig including its instrumentation has started.
- The first CRTF design has been carried out and the manufacture of all the test bench component parts has been launched.
- Design and manufacture of the Booster test bench parts for High Loaded Scale down booster realised. Numerical simulation of the rotating stall booster has been validated, and Aeromechanical design for DDTF & high-speed booster realised.
- Hot and cold Structures weight reduction reached already partial objectives. Current status is as following:
- For composite 25%
- For titanium fabrication 13%
- For hot structures 15%
- Metal Matrix Composites (MMC) samples for low pressure shaft have been manufactured and tests started and tests on MMC-steel joint have been performed.
Low Pressure Turbine
- Ultra High Lift Airfoil: CFD 3D design and parametric optimisation completed
- Ultra High Stage Loading: A linear cascade test performed
- Ceramic NGV: CAD model achieved to deliver specimens for the test campaign expected in early 2006
- A cascade low noise airfoil design tests started at UPM facility
- A cascade rig layout finalised to allow implementation of selected active control features
- CFD characterisations of aerodynamics jet of a high BPR engine installed on the aircraft started with a nozzle baseline and with a low noise nozzle. The specifications and the recommendations for Wing Tunnel Test have been performed for isolated and installed VHBR Nozzle.
Thrust reverser (T/R) target efficiencies have been established as a function of the BPR for VHBR engines, in order to adapt the T/R design criteria.
