Update – 6th December 2019
We’ve been to Manchester University to supply them with a set of blades and a rotor for scanning and modelling. The 29 blades were removed from a Rolls-Royce Viper Engine. This engine was chosen because the blades are made from steel which will allow them to be excited using a magnetic field whilst spinning in the test rig.
Thanks to Ben at Vapourworx surface solutions for the great job of cleaning the blades and disk.
Update – 16th December 2019
We’ve been back to Manchester University to supply them with another set of blades and a rotor for scanning and modelling. We now have three complete rotors from two Viper engines, all with steel blades
Thanks again to Ben at Vapourworx surface solutions for another great job of cleaning the blades and disk.
Update – 29th January 2020
We have returned from a visit to The Institute of Thermomechanics Academy of Sciences of the Czech Republic (IT ASCR) in Prague. The purpose of the visit was to review the test requirements and see the spinning rig first hand. This was a very positive visit and we are on plan to get the Viper Rotor on the rig later this year.
Update – 9th March 2020
The preliminary blade mode data has been imported into our axial position calculator. This calculator will help determine the axial position of the probes above the blades. For more information see the relevant section of the Editor Manual in the downloads section. There you can also find a sample file for the mode information. This information is subject to change as the project continues.
Update 11th May 2020
The equipment for Batista is commissioned and undergoing testing. The picture shows the following equipment.
Acquisition, Lasers, Power Supply, simulator and variable reluctance conditioning units. All of this equipment is networked and controllable from MultiTool software. The simulator is driving the laser receivers optically across a small air gap. More information is available on request. email@example.com
Update 4th June 2020
The telemetry system design is complete. We have a custom 15 channel unit designed to interface directly onto the rig. The telemetry for Batista is undergoing commissioning and testing. Below is the PCB for the end of shaft design and this can be seen in the rig adapter design below. The blue area is the telemetry unit. To the right is the blades are marked ready for strain gauge placement.
Status update for the spinning rig in Prague.
Here is the configuration for the rotor. All of the parts will soon be in manufacture and we can see the multiple probe holders for the various probes and the excitation magnets. We are looking to add more magnets at present.
More information is available on request. firstname.lastname@example.org
Update 29th June 2020
Manchester University remains in lockdown due to Covid-19 but are hoping to open up the labs shortly to continue with the blade calibrations. The telemetry system for Batista is commissioned and undergoing calibration using our bespoke Telemetry acquisition software. More information is available on request. email@example.com
