Advanced Gas Turbines (LDI)

[rawdude]

Hi, <br> I am in search of information pertaining to advanced gas turbine engines. In particular, I am interested in locating articles, web sites, companies, or anything that will give me information pertaining to lean-direct injection (LDI). This is a process that is currently being researched which will increase the pressure and temperature of a gas turbine engine while keeping the NOx within expectable limits. The only information that I currently have is from the mid-90’s. This information stemmed from research being done at NASA for High Speed Civil Transportation. Any ideas would be greatly appreciated.<br> <p>Ross A. Watters<br><a href=mailto:ross_a_watters@hotmail.com>ross_a_watters@hotmail.com</a><br><a href= > </a><br>

I suggest page (216) of Mechanics And Thermodynamics of Propulsion. The book is a text of my school days. The company of print, Addison-Wesley Publishing Company, Inc. Have fun the math is very good. philnadep

 

Contact Rolls-Royce. Rolls-Royce Canada has developed a very large industrial engine with just such low emission and lean burn standards in mind but it is a lower temp and natural gas fuelled engine.
We have also devised ‘trans-ply’ combustion liners that substantially reduce NOx in higher temperature engines. (For the Tay 611-8 / 650-15 and Spey 511-8 [optional].) The principal is very simple though I’m sure the fine-tuning of the airflow is not. It does not meet your criteria in that the fuel mixture is not leaned in any way but it may still provide insight.
Hope this helps your quest, Ken.

 

Humm, just looked at our respective dates of submission. Seems I'm two years too late with my reply. I trust you haven't been waiting that long.

Ken.

Worse engine there is for fuel consumption. If there are any Boeing or other aircraft engineers here. Think about going back to recips for short commuter hops. A properly designed recip will do lest than half the fuel consumption of a turbine or jet. If speed is a factor look at the P-51 Mustang and P-47 XP-72, both could cruise right along side a 767.
