First set of wings

Posted on Jan 2, 2018

January 2018 seen a very productive month for the FLEXOP consortium. The first set of wings (-1) have been finished, including assembly and painting and are ready to be shipped from FACC to TUM, where final assembly will take place. In the meantime the consortium has met in Münich to discuss the necessary test procedures for ground testing and flight tesing. A detailed test plan helped the interdisciplinary team to understand the requirements of each stage. In parallel with the meeting the avionics integration also progressed, since the SZTAKI team worked onsite maturing the “Iron-Bird” of the demonstrator airplane.

Wing instrumentation

Posted on Dec 22, 2017

Wing instrumentation, including fibre brag sensors, inertial sensors and actuator power supply cables, including the control databuses have been integrated into the first two pairs of wings. The baseline rigid wings (-0) will be used to test several concepts, including shape and load monitoring with fibre brags with a few hundred measurements in each wing. In addition, the reliability of the 12 wing mounted 3 axis inertial measurement units and the actuators will be tested using these wings. The second set includes mounting points for the high-speed direct drive actuator, which will be also flight tested first on the -0 wings before mounting them on the very flexible -1 wings.

Sixth Consortium Meeting

Posted on Dec 5, 2017

Our Sixth Consortium Meeting was held on 23-24 November 2017, at AGI-G, Münich, Ottobrunn, Germany. Mathematical models of the aircraft has been updated by CFD data and ready for testing the baseline (rigid body) control laws. The corresponding control methodologies have been matured and showed promising results in various simulation studies. The fuselage, actuators and sensors are manufactured, their assembly with the first set of wings will begin soon. Avionics hardware and software show great progress with the first hardware-in-the-loop simulations. Preparation for the hardware integration, mock-up testing and ground vibration tests began. The Scientific Advisory Group gave recommendations about sharing data among partners and project management but overall gave positive feedback about the ambitious goals and achievements of the project.

Visit at TUM

Posted on Aug 21, 2017

A two day working meeting (10-11 August 2017) took place in TUM with the participation of several members from SZTAKI working on the avionics components of the airplane. The focus of the work was on the EMC mockup, where all flight control actuators and the corresponding flight control computers (FCC) and cables are tested to show proper functional behaviour. In addition the teams showed significant progress in engine integration as well, where the engine specific protocol was tested and the FCC – engine datalink has been successfully implemented. The two teams have scheduled several follow up meetings to finalize the telemetry, autopilot and navigation sensor simulation platform, before the aircraft can commence its maiden flight.

Visit at FACC

Posted on Aug 21, 2017

As the first set of wings are reaching assembly status SZTAKI visited (9 August 2017) FACC to get better insight of the manufacturing process and finalize the cabling and actuator layout within the wings. During the visit several topics have been discussed related to additional needs for cable routing and the schedule was updated based on the discussion with TUM and INASCO. The integration of flutter IMUs into the wings was another topic, where different topologies have been established for the carbon fibre (-0,-2) and glass fibre (-1) wings. The teams have concluded with the schedule for further integration tests, where INASCO and TUM will also participate.

5th Consortium Meeting

Posted on May 24, 2017

Our Fifth Consortium Meeting was held on 18-19 May 2017, at INASCO, Athens, Greece. The detailed design of the demonstrator is almost complete. Critical design questions related to -1 (flutter) wing have been discussed. The demonstrator manufacturing and integration is progressing according to the schedule. Experiments with the high order aircraft mathematical models are showing good progress. The scale-up task is also well aligned with the project objectives. The Scientific Advisory Group gave recommendations about modelling, control design and project management but overall gave positive feedback about the ambitious goals and achievements of the project.

Work Package Meeting

Posted on February 22, 2017

During the meeting RWTH and AGI-G reported about the status of setting up the baseline aircraft model and the recent findings related to performance gains, how we would be able to reach the performance promises of the proposal. We also looked over the present status of the project and came up with a sensible plan reflecting our current knowledge about executing the project plan in a feasible manner.
Moreover, we went through all the testing phases of WP4, including the groun, hardware-in-the-loop and flight test schedule, to be able to come up with specifications for each item.

Closing The First Reporting Period

Posted on December 2, 2016

FLEXOP project is closing its first reporting period and the first project review was completed successfully. According to the first remarks of the reviewer, professor Dean Vucinic (Vrije Universiteit Brussel, Faculty of Applied Sciences, Department of Mechanical Engineering) and the Project Officer, Hugues Felix : the project is running with well organised work and harmonised consortium. The delay showing in the developments of the three sets of wings can be justified by the fact that FLEXOP is aiming at a very ambitious goal of building a flying demonstrator rather than providing simulation studies only. They encouraged the consortium to advertise the project for a wider audience, including the general public with special focus on teenagers.

Fourth Consortium Meeting

Posted on December 1, 2016

Our Fourth Consortium Meeting was held on 28-29 November 2016, at TUD, Delft University of Technology, Netherlands. The baseline aircraft wing is complete and the related aeroelastically tailored wing is also in good shape. Both of them are nearing manufacturing status. Several discussions were held how to proceed with the flutter wing, which is still not ready due to its highly multidisciplinary nature, and due to the sensitivity of its design to material parameters and flutter tuning masses, which has to be investigated in more depth before freezing the design. Several results related to flutter control have been presented and their corresponding dissemination activities are progressing well. Mature concept of the avionics system, including its physical components have been finalized and the aircraft is ready to be built. The flight testing and scale-up objectives have been discussed in detail and the consortium has a clear agenda for the upcoming period. The partners had the opportunity at the Department of Aerospace Structures and Computational Mechanics to visit the laboratories of the Faculty of Aerospace Engineering.

Third Consortium Meeting

Posted on July 4, 2016

Our Third Consortium Meeting was held on 28-29 June 2016, at DLR, Oberpfaffenhofen, Germany. The detailed design of the demonstrator is progressing well. Critical design questions related to wing fuselage interface, function of -0 and -2 wings, and the avionics concept are resolved. Within WP2 the different layers of modelling are agreed between the partners and the responsibilities are clear. The Scientific Advisory Group gave positive feedback about the technical progress of the project but advised to keep the schedule more tightly.
