Periodic Reporting for period 2 - HYDRO_RIG 3G (Development of a hydraulic installation for electro-hydraulic integration of hybrid surface actuation systems in on-ground rigs)
Reporting period: 2018-12-01 to 2020-05-31
The project HYDRO_RIG 3G has been conceived to develop an A/C representative hydraulic installation that integrates all the A/C hydraulic system equipment, considering hydraulic generation and hydraulic distribution, and the corresponding sensors fully representative of flight test instrumentation (FTI), in order to reproduce complete A/C conditions that will be present in the Regional FTB#2 Demonstrator, regarding to the actuation of hybrid surfaces as ailerons. The system is fully representative of A/C environment like volume, pressure loss, etc. For this, it is necessary to simulate all components that integrate the system. FTI sensors are installed with a wireless system as shown in Figure 1.
HYDRO_RIG 3G will contribute to test operational conditions combining hydraulic and electrical compounds in those systems that ensure an increase of the electrical control without negative effects between both of them, in order to reduce weight and volume of the equipment, saving fuel and hence contributing to the reduction of fuel consumed to reach the targets set by FlightPath 2050: 75% reduction in CO2 emissions per passenger kilometre and a 90% reduction in NOx emissions."
- Simulations of commercial elements until reaching an almost complete similarity of A / C conditions.
- Manufacturing of a hydraulic installation based on the previous simulations.
- Manufacturing of an HVDC electrical network for the management of A / C surfaces.
- Start-up of a wireless system for FTI sensors.
- System for the interconnection, switching and automatic cutting in patching panels.
- Integration of different operating modes: stand alone mode and integrated mode.
- Manufacturing of a signal acquisition and control system capable of monitoring the entire bank.
Hence, a bank capable of reproducing the electro-hydraulic conditions of the aircraft has been achieved (Figure 2), integrating both A / C equipment and simulated equipment for the control of surfaces (aileron, spoiler, flap and winglet).
The impact market of this development could range anywhere from design departments of manufacturing companies, TIER 1 and companies subcontracted for the manufacturing of structures.
HYDRO_RIG 3G developments offer applications of wireless technologies in a market dominated by technologies of structured wiring. HYDRO_RIC 3G offers the major advantage of wired technology (security connection) but without the two major drawbacks off current technology: the high weight and the difficulty of assembling.
The project allows to elaborate patterns based upon real acquired and elaborated parameters that describe the system operation and allow to define maintenance intervals and to reduce the workload of FTI engineers.
Currently available test systems require the action of technical personnel to simulate errors, or perform signal reading and mainly to bypass when signals can be generated by various sources, simulated by an external system or read by various devices under test.
With HYDRO_RIG 3F system, we will be able to have a first solution, which should be evolved subsequently, to make this process automatic, allowing a great time saving for test developers and to include more variables to the system, thus they can more reliably detect possible errors both in the HW and SW of the units under test.
