The work performed is broken down to the following work-packages.
WP1 is the project management inside SARAH. Standard project management tasks have been performed which are detailed in the interim technical report (D1.1).
WP2 focusses on the method development, concentrating on novel analysis methods and process for improving safety of airborne vehicles.
Progress in WP2 has been achieved and documented in details in D2.1 and D1.1. In particular it includes the following major highlights:
• delivery of “open” (not IP-restricted) geometries used for benchmarking
• support for design of test-specimen (WP5) w.r.t. loads calculation
• setup of tool chain for coupled high-fidelity helicopter and aircraft simulations
• improvement of low-fidelity simulation tools
• implementation of means to simulate waves
In the second project half progress with regard to finalization of the fully coupled high-fidelity simulations will be achieved as well as the finalization of WP2 with regard to improving low-fidelity tools.
WP3 includes the analysis of physical effects during ditching for academic conditions (still water and simple kinematics).
In Wp3.1 a model with rigid and fixed floats has been built and a ditching case in calm water has been simulated. Loads for dedicated components have been delivered to support the WP5 mockup. Simulations in waves have been performed with the Rienecker & Fenton nonlinear regular wave model as well.
WP 3.2 tackles the ground aerodynamics, in particular the ground effect, with regard to its impact on water emergency landings. The work performed by TUHH concentrates on adaptations of the code ditch, which are based on high-fidelity CFD-calculations to understand the impact of the ground effect on the overall lift.
WP4 addresses design solutions to increase safety of conventional and unconventional aircrafts and helicopters.
In WP4.1 concepts for energy absorption solution have been prepared and delivered for A/C and H/C.
The activities in WP4.2 were started earlier than anticipated in order to cope with deviations occurring in other Work-Packages. At the current stage first ditching simulations on a Blended Wing Body configuration have been performed and currently tool updates to improve the simulation are implemented.
WP5: Activities are devoted to updates on both test-facilities used in SARAH.
In WP5.1 (Helicopter tests) the following progress has been achieved:
• Definition and helicopter geometry and realistic loading conditions
• Definition of the instrumentation matrix, chain of measurements and test-matrix
• Finalized project for the guiding system, imminent order
• Last phase of design for helicopter
• Last phase of design for the EFS (imminent order)
• Full planning for the experimental campaign
In WP5.2 (Aircraft tests) the following progress has been achieved:
In the first half of the SARAH project CNR-INSEAN has put most of the effort in the preparation of the experimental setup for the conduction of experiments on Task 5.2. More specifically, the activity concerned:
- Improvement of the facility for safer, faster and more reliable test execution
- Design of the specimen for T5.2.1 and T5.2.4
- Design of the experimental setup for T5.2.4
- Design of the structural component for T5.2.2
- Preliminary definition of the specimen for T5.2.3
- Built of the specimen to be used for T5.2.1
- Preparation of the experimental setup for T5.2.1
WP6 is aims at exploring the full benefits derived in the technical WPs2-5. Major activities occur in the second project half, so far model building activities in WP6 are active to deliver a nonlinear, realistic aircraft model to be used to be used for high-fidelity simulations in other WPs.
WP7 is dedicated to the monitoring, management and reporting of these activities.
A Plan for the Dissemination of project Results (PDR) was delivered and updated. The project visual identify as well as diss. material was distributed.
