HIDRO_RIG 3G (wireless)
The general concept behind the HIDRO_RIG 3G is the performance test of the surfaces of the aircraft. These surfaces may be operated by hydraulic and electrical systems, and can thus be a comparative thereof. This hydraulic rig is crucial to understand the interrelationships between the systems flight performance surfaces electrically and / or hydraulically powered.
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 .
Hence, a bench 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.
HYDRO_RIG 3G has developed an electro-hydraulic rig capable of varying the pressure loss of the branches that go to consumers. The rig allows software control and perform optimization models to reduce in flight losses and thus improve the consumption.
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 bench 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. HIDRO_RIG 3G is able to perform all tests in automatic mode, which allows a great time saving for test developers and include more variables in the system, so they can detect more reliably posible errors in both the HW and in the SW of the units under test.
