    New Zealand Engineering (Aerospace/Mechanical)

    Thanks a million guys, that's more than I could have asked for! RocketLab would be my number one, I came across them before, seems like they'd be pretty tough to get into though. But alas, I will persevere!

    New Zealand Engineering (Aerospace/Mechanical)

    Hi Guys, I'm assuming this is a bit of an ambitious question but here goes. I'm an Applied Physics (B.Sc) graduate, and have been working for an Aviation MRO in Ireland for the past year since graduating from university. Aerospace is my industry of choice at the moment, but my real goal is to...

    RVDT Replacement

    Cheers for that VE1BLL, the sterling always comes back to bite anyone not from the land of said currency! Jraef, I see where your coming from but the unit is from an aeroderivative gas turbine so I'm assuming the engine will be running on aircraft supply, i.e. 400Hz..we only repair the...

    RVDT Replacement

    Is that reliable info?!..

    RVDT Replacement

    Thanks for all the input guys, just in case anyone else comes across this problem in the future, we received got a quote from Sensonics.co.uk to build a custom RVDT for us. No exact numbers yet, they indicated the 4 figure range but nowhere near the $15k mark. Finally some progress! I hope this...

    RVDT Replacement

    VE1BLL, your exactly right, that's one of Kavlico's Aircraft units, hence the price. And there's our problem, we don't have capability in house to repair them. Does anyone know of any places that repair RVDT's? I really didn't think that such a widely used type of sensor would pose such a problem...

    RVDT Replacement

    VE1BLL, thanks for the "bible" info, it's really helpful. Just got a quote from Kavlico of in and around $15K for a new unit (from their Aero product line), you can see my frustration! Surely if 26VRMS 400HZ is common as dirt I should be able to come across one for cheaper than this right? We've...

    RVDT Replacement

    Thanks for the concern VE1BLL, but its actually an industrial application, so no need to worry! Byrdj, thanks for the info, been onto Kavlico already, their product doesnt really match our needs but Moog's unit might be worth looking at.

    RVDT Replacement

    Hi all, We have a unit in on which the RVDT is broken and Woodward MPC no longer manufacture the unit. Its a 26 VRMS 400 Hz single channel sensor that measures the angular position of the shaft on a throttle valve, that rotates through a range of 90 degrees. I've gone to nearly every OEM I can...

    Specific Gravity vs Flow Rate

    Hi guys, Ok, thanks a lot for the extensive replies. It seems however the discussion has spiralled slightly beyond the scope of my question I think. I think my description of "I change(on a test rig for valves etc) from using one oil to another oil" was slightly misleading. What I meant by...

    Shell JP-5 Alternative

    Hello, Can anyone suggest a suitable fluid to use when testing a unit that runs on Shell JP-5 (Mil-T-5624J)? We normally test units on our rig with Aeroshell Calibration Fluid 2. I've contacted Shell themselves to see if there is a similar calibration fluid equivalent to JP-5 but there are less...

    Specific Gravity vs Flow Rate

    IRStuff, Sorry yes, I just realised I'm talking volumetric flow rate here so clearly it is viscosity and not specific gravity that an oil change would have on flow rate right?

    Specific Gravity vs Flow Rate

    Hi, Just a quick question, if I change(on a test rig for valves etc) from using one oil to another oil that has a different specific gravity, and I need to supply a particular flow rate, do I need to account for the change in specific gravity in my flow rate, assuming pressure drop stays the...

    MIDLAND ROSS CO MANUALS

    Does anyone know what actually happened to Midland Ross Co and if so, is there ANYWHERE someone could suggest to go to procure and IPC for a Shut-Off Valve manual? The internet search is proving particularly fruitless.. Thanks

    Viscosity Change Calculation

    Hi. We have an axial piston variable starter motor in that we normally get sent out for test but are looking into testing ourselves on our own rig. The manual calls for a calibration fluid of a particular operating viscosity (16-36mm2/s) when carrying out the test. The problem is, our rig uses...

    McLube 1720L

    Hi Guys, First post here so if I've left out any information let me know. We received a manual for repairing an aspirator hose assembly that requires the use of McLube 1720L. I was wondering does anyone know a suitable alternative for this material? There seems to be very little on the net about...

    Hi Guys, First post here. Just wondering, I have a manual for repairing an aspirator hose assembly that requires the use of McLube 1720L. I was wondering does anyone know a suitable alternative for this material? There seems to be very little on the net about this particular P/N as opposed to...
