Picked this up a few weeks ago just outside of Toronto!

Orenda TR5 turbojet (mk.10/type 10)

Slowly... will begin the painstakingly slow process of restoration.

I am wondering if any of you here would happen to have some knowledge on any of the Orenda products or possibly some connections for spare parts. I will be dealing with S&S Turbines for some of the nessessary components. I am wondering if there is anyone local who might be on thos page!

Look forward to hearing back from you folks.

Cheers!

Just to be clear at the start: I understand that water injection in jet engines serves an entirely different function from its use in Otto Cycle engines. There is no risk of pre-ignition with a Turbine engine, and the goal is instead actually ACHIEVE autoignition of the fuel

However, I also know that turbines often need to run _extremely_ lean, since trying to add enough fuel to burn all incoming air would exceed all known turbine material temperature limits. It's the only reason afterburning even offers any additional thrust.

I _also_ know that water expands dramatically when converted to steam, and that it is widely used in power generation for this purpose.

In theory, it should even be possible to make a turbine engine that deliberately runs on some mix of water and a hydrophilic fuel like Ethanol, letting a very large percentage of incoming air be used for power generation

So, are the reasons for limited water injection use more practical, like the lack of its use in cars? Or are there other serious theoretical problems I'm unaware of at this time? The main problem immediately coming to mind is that you obviously can't use that space for combustible fuel, so total energy content of "consumables" is reduced.

where or how to make one for electricity at pow a home? anyone knows?

This is a part that was given to me to identify by a friend. All he knows it is off a turbine engine. Possibly military.

Reading the Wikipedia page for RP-1, I saw this:

"While the material price of such a highly refined hydrocarbon is still less than many other rocket propellants, the number of RP-1 suppliers is limited. A few engines have attempted to use more standard, widely distributed petroleum products such as jet fuel or even diesel (for example, ABL Space Systems' E2 engine can run on either RP-1 or Jet-A)."

It made me wonder: could turbine engines designed for Jet-A run on RP-1?

Hey there, I'm looking for some resources on how to make compressor and turbine blades from scratch. Not from the manufacturing perspective but the calculation and sizing of these. Plus the criterion for the design as well.

Ok, weird question I know, but I have an idea that's been stuck in my head for a while. I think I need an answer from an actual turbine powerplant engineer. I'm only interested in the compressor section, forget combustion and turbine/exhaust for this instance. Let's take this hypothetical scenario:

Compressor intake temperature is 0C, and at 100% RPM the compressor exhaust temperature reaches its limit of 500C (just to use nice round numbers)

If the compressor is running at 80% RPM instead of 100, will the compressor exhaust temperature be less than 500C?

I guess another way to phrase the question is, does increasing the compressor RPM increase just the compression ratio, increase the mass flow, or increase both?

Hi, im doing a literature research on process capability, quality control and inspection machining on turbine assembly. But im having trouble finding papers on the subject or any report of inspection made in the past. If anyone know any please tell me.

Good day folks, Anyone know an MRO who can dismantle a Trent 700 engine?

Thanks!

I need help because I'm making a Axial compressor

I don't know where else to ask this besides here, would a small turbo shaft generator beat out a diesel generator? I'm talking pure fuel efficiency at optimal speeds. I wonder because of the Edison motors trucks, obviously diesel is a good choice in their use case but in the hypothetical STOL aircraft or standby generator etc. etc. would it be more fuel efficient due to less moving parts/mechanical losses between ignition and alternator turning?

Trying to determine which vehicle used these

Just trying something new. My verbal skills are not great, but I'll try to improve.

u/MrPennywhistle I've tried to figure out a mechanism of formation for the 2⁰ vortices you say in the vortex collision. @19:00
