The AhEAD work plan has been developed according to the Project Logical Framework described below.

To achieve the Project's objectives a number of actions have been identified and organized in 6 work packages:

  • WP1 – Project Management, has the aim of supervising the project implementation and ensuring the activities are effective in reaching the project objectives and the expected results;
  • WP2 – Problem assessment and requirement definition, has first of all the aim of reviewing and agreeing with the Topic Manager the scope of the work and the Project program. Further, it has the goal of identifying all the requirements of the application in object from which the antenna specifications that will drive the next steps of the Project will be finally assessed. Minimum expected performance with respect all possible radar operation modes (ATSR, STSR) and avionic constraints (environmental, standards, weight and size limitations, system performance expectations, compatibility and interfaces) will be considered as a minimum. The proposing Team will collaborate with the Topic Manager in order to correctly address the problem, also considering specific needs of the Topic Manager;

    Development and design validation is made by implementing 2 WP’s:
  • WP3 – Antenna design, this part of the activity will start from the analysis of the state-of-the-art, in order to identify possible technological solutions to be traded-off. Two candidate solutions (indicatively) will be identified to be worked out up to the level of “Preliminary Design” and their performance (evaluated through detailed full-wave modelling) will be compared in order to select the most promising configuration, which will be further worked-out up to “Detailed Design” level. Also mechanical and thermal issues will be considered in parallel, aiming at identifying a final configuration of the antenna, whose performance will be again evaluated by referring to the same detailed numerical models used for design. A breadboard configuration (representative of the antenna functionalities and critical issues) will be defined and manufacturing drawings will be produced;
  • WP4 – Antenna breadboard manufacturing & testing (measurement): the breadboard configuration identified in WP3 will be manufactured and its electrical and radiating performance will be measured in suitable measurement facilities. The measured data will be compared and integrated with the simulated ones in order to complete the validation of the antenna design. Thermal cycles and stress test (as defined by the relevant avionic standards) will be also executed in order to verify the applied antenna technology;
  • WP5 – Design evaluation. Assessment of a roadmap for full device development, aims at concluding the Project, by at first reviewing the antenna design performance, critical issues etc. and then objectively evaluating its effectiveness to satisfy the requirements for polarimetric aircraft weather radar applications. A roadmap will be delivered to trace the path towards full antenna implementation, starting from the available design configuration, also considering qualification and certification activities. Technological gaps and aspects to be possibly deeper investigated will be identified. Also in this step “CleoSim”, the tool realised within the CLEOPATRA Project, will be applied to support the Team in the evaluation of the design, by considering the scattering from realistic meteorological phenomena;
  • WP6 – Dissemination, is the WP dedicated to define and implement a communication strategy among the stakeholders. A Project Web Site will be created at the end of Month 3 and other communication activities will be implemented till the end of the project.

The duration of the project will be a total of 18 months.
