The GABRIEL project had its final review meeting held in Brussels on 28th 29th August 2014. The participants have discussed the recently closed work packages and the related deliverables. 
The first day of meeting started at 10 am 28th of August, 2014 according to the agenda. Prof. Rohacs, the coordinator of the project has started the meeting with the introduction. Professor Rohacs He mentioned that the Gabriel project was running for three years and now it is close to end by the final consortium meeting and the final review meeting (Day2).
The meeting started with those work packages where the focus of the work was in the second period with some deliverables closing only recently. So the first presentation was related to WP4 – Concept Validation.
The first presenter was Norbert Siepenkötter from Aachen. He presented:  D4.4 – Ground system specification and development.  
The next presenter was Cesari Szcepanski from Wroclaw on D4.8 – Evaluation of the test results.
The presentations continued with WP5 – Impact assessment. The presenter was Andrzej Majka from Wroclaw and the subject was D5.2 – Emission and greenhouse effects related to the GABRIEL concept.
Peter Schmollgruber from ONERA presented D5.3 – Effects of GABRIEL Concept on the air Transportation Sustainability. He described the calculation on environmental benefits from a wider dimension: energy, global warming, atmosphere acidification and disposal/recycling (waste) were angles of the analysis. Besides there were a life cycle approach from manufacturing through operation to disposal the whole process was considered, including the difference between a traditional concrete runway and a maglev one. The benefits are clear despite the fact that GABRIEL followed a conservative approach when measuring the environmental benefits.
Marcello Amato from CIRA showed the results of D5.7 – Safety concept deliverable. daniel rohacs
Prof. Rohacs from REA-TECH did the presentation on D5.8 – Security problems.
Frans van Schaik from NLR presented the D5.9 – Integration aspects and critical areas. As he mentioned this task was a kind framework task for many activities for GABRIEL as it shows the operational scenarios of the system at the airport and in the air. He referred back to the workshops with pilots (NLR 2013, SLOT 2014) and on the bases of that and the analysis he concluded that although it is difficult to judge the future in detail, it is likely that the GABRIEL system will have no major influence on the coming ATM system, it can fit well.
The final review meeting took place on the 29th of August 2014. Mr. Eric Lecomte the project officer attended the meeting from the European Commission and Mr. Pablo Perez-Illana (EC) attended partially.
The review meeting presentations started with the Welcome by Prof. Rohacs, REA-TECH and Introductory presentation – Daniel Rohacs, (REA-TECH).
That was followed by presentation on WP3 –Theoretical Investigation by Mark Voskuijl (TUD) and WP4 –Concept Validation by Norbert Siepenkötter from (Aachen) and Dieter Rogg.
The presentations were continued by WP5 – Impact Assessment delivered by Daniel Rohacs (REA-TECH), Marcello Amato (CIRA), Ad de Graaf, (ADC) Frans van Schaik (NLR) and WP6 – Dissemination and Exploitation by Roland Guraly (SLOT) and Ad de Graaf (ADC).

The main results of the project are shown below. 
  • Concept was validated on a maglev track, results were quantified
  • GABRIEL provides outstanding benefits (savings):

Area of benefit



9.3% saving for take-off weight, 18.1% for total fuel weight

Fuel consumption

79.6% reduction for take-off, 8.2% for the en-route, 60% for the LTO

Emissions at the airport region

decreasing by 58% CO2, 60% NOX for LTO

Noise at the airport region in terms of area affected

reduction by 64% for take-off, 19.7% for landing


increasing by 8.75%

Cost-benefit- total cost savings per cycle

total cost savings per cycle 1.579,26 €

  • The concept needs further analysis on the following items:
    • rendezvous control system, emergency landings,
    • airport flexibility aspects (stand-alone or combined operations, benefits),
    • suitability for different kind of aircraft
    • cart-sledge system and the connection mechanisms,
    • certification issues.
    Eric LacomteThe meeting concluded with the presentation of Mr. Eric Lecomte. In overall the Commission is satisfied with the in time delivery and the content of the reports.

    Workshop on ILA Berlin 2014

    In the frame of the ILA Berlin Air Show 2014, the GABRIEL consortium had its workshop with ILA Berlin Air Show logothe participation of GABRIEL User Group members. The workshop was organised by AD CUENTA BV – Netherlands with the support of all consortium members.

    The consortium introduced in detail the GABRIEL concept and presented the work done in the frame of the GABRIEL project.

    The agenda of the workshop was as follows: 


    Reception of guests, coffee

    The consequences and benefits for the aircraft configuration by P. Schmollgruber



    Flight safety, environmental impact by Angela Vozella  



    Dr. Rohacs presentationThe FP7 GABRIEL project  focuses on the feasibility and preliminary design of a system to launch and recover medium sized aircraft on a track powered by Magnetic Levitation. Such a system will allow a substantial saving of fuel since the aircraft weight can be reduced as no landing gear is needed, no undercarriage fairings are needed which also reduces drag and smaller engines can be used. This will result in substantial savings in fuel cost and lower CO2 emissions during take-off and landing as well as cruise. Further cost savings are possible as no maintenance is needed on the landing gear and engine thrust reversers.  Thanks to ground power assisted take-off, the emissions and noise at and near airports can be reduced as well. The cart on which the aircraft is placed will allow electric taxi at the airport and autonomous push back from the gate, thereby further reducing emissions and cost. 

    The GABRIEL project investigated the following issues:

    • Design of an appropriate MAGLEV system and the sledge that is attached to the MAGLEV ramp
    • Design of a cart that will connect the aircraft with the sledge
    • The design of appropriate flight control systems to make automated precision landings
    • Small-scale demonstrations to validate the concept
    • The safety issues connected to the proposed solutions both related to passengers and flight safety, the security issues and certification
    • Solutions for emergency landings of aircraft without landing gear
    • The environmental impact assessment
    • The usability of the system at large, small and regional airports as well as for inner city locations
    • The cost benefits of the proposed system compared to current practice.

    The conclusion is that the concept results in large cost benefits, saving of scarce aviation fuel and reduction of CO2 and noise at the airport. IATA also supported this conclusion. It is highly recommended to continue European research and investigations into this aviation step change and to continue with a detailed design effort. The project also showed that in some areas like automated precision landings further research and development is needed.

    The consortium has prepared a leaflet for this occasion:

    Progress meeting in Wroclaw

    The GABRIEL consortium had a successful progress meeting in Wroclaw Poland. The meeting was hosted by the Wroclaw University of Technology. The University belongs to the best technical universities in Poland – over 35 000 students study here under the guidance of 2 000 academic teachers, at the 12 faculties and the Department of Fundamental Studies, as well as in the 3 regional branches (Jelenia Góra, Legnica, Wałbrzych). It rates high in the annual rankings of Polish universities. Recently, it has been announced the best Polish technical university in Webometrics Ranking of World's Universities.

    ILA Berlin logoThe goals of the meeting were to evaluate the progress of the project, to get familiar with the test bench built by the polish consortium members and to discuss the upcoming GABRIEL Workshop to be held in the frame of ILA Berlin Air show 2014 on 20th May.

    Laboratory photoThe consortium members have visited the laboratory where the 9 meters long MAGLEV track being built and become familiar with structure of the track and the sledge that using it. They also discussed the software that controls the installation as the Aachen University is building the model aircraft that will land on the moving sledge and also has created the software that controls the landing. For the successful experiment those two applications should communicate with each other and synchronise the movement of the model aircraft and the sledge on the magnetic track.


    In the laboratory the consortium members also have seen the UAV built by the Wroclaw University’s scientist that is capable of autonomous flight. It flights from one predefined point to another using GPS data and avoids obstacles in the process by using on board video and laser equipment. The predefined points could be change during the flight remotely so that the destination or route of the UAV can be changed during the flight.

    Laboratory photoThe scientists of the Wroclaw University also have showed the water tunnel that allows making experiments with aircraft and wing shapes providing better visibility and data at slower speed that the wind tunnels usually.


    GABRIEL in Rome

    The GABRIEL consortium had its regular progress meeting in Rome organised and hosted by CIRA on 19-20 September. The goal of the meeting was to discuss the progress achieved during the last period and to synchronise further actions. Beside that the new design of the magnetic track was discussed that will allow lower energy consumption and decreased requirements for the power chain yet simultaneously providing enhanced lateral stability to the system. The new aircraft modifications were also discussed that allow further fuel saving thus resulting lower emissions.

    ATOS Conference participation

    Representing the GABRIEL project Mr Daniel Rohacs has delivered a presentation on “Preliminary Evaluation of the Environmental Impact related to Aircraft Take-off and Landings supported with Ground Based (MAGLEV) Power” on the ATOS Conference that was organised in Toulouse, France on 8-10 July 2012.
