Looking Southwest across Puget sound from one of my favorite vantage points, A west (homeward) bound ferry.
Got something more than just the solid grey canopy we usually have this time of year:

I've been spying on you (sorry no clouds)


On 787. What's the difference between GE and RR engine?

Internally I guess not much. but when it comes to price, fuel efficiency and reliability that's where differences may be.

That's a great shot of the Seattle shoreline,
And a Bainbridge boat in the center of the shot (but headed east)

From April 2017 at Lake Grapevine TX. I've posted a few other shots of this sunset previously

I appreciate the input. Thank you NS Sailor

Thank you. Oh They shuffled the boats around and confused me with a Bremerton boat

I like it!! Great shot Paul

Another clouds over Puget Sound

The smaller, west bound boat in your shot is going to Bremerton, the bigger, east bound boat is a Bainbridge vessel, (either the Tacoma or the Wenatchee).

GE is General Electric.


RR is Rolls Royce.

GE is General Electric.
RR is Rolls Royce.

Yes. I was wondering if there are any performance difference between GE and Rolls such as cruising speed, flight range etc

Taks,

In general, engines from both manufacturers are available for most commercial aircraft. Each engine manufacturer (i.e. GE, RR) designs the engines to meet the stated engine specifications from the aircraft manufacturer. This is in terms of engine size/weight, attachment fittings, thrust, fuel consumption, reliability, etc. Each airline is free to select an engine meeting those requirements from either GE or RR. Which engine they select generally depends on things like price, engine thrust and specific fuel consumption, which can be traded off depending on things like the routes to be flown for the particular airline. All of that being said, each engine manufacturer has their own proprietary techniques used in the design to eke out every possible ounce of performance. The internal guts of each manufacturer's engines will be similar, but not identical. For instance, the number, and dimensions, of the engine blades and the number and position of the blade assemblies will usually be different. Each manufacturer will design towards the same specifications, so given the same basic technology, the engines will be similar (at least from an external viewpoint) and will have roughly the same performance.

Hope this helps, although I suspect I've just managed to through a little confusion into things!

These shots were taken last week in Naples, FL as the sun set through the clouds over the Gulf of Mexico. they were taken with my K-3ii and either my HD Pentax-DA 16-85mm F3.5-5.6 ED DC WR or my HD Pentax-DA 55-300mm F4.5-6.3 ED PLM WR RE and are part of a series of about 100 pictures.
