As the Andrew spend their working lives working in, on, under and above the medium which your Prune name suggests you are master of, I suspect they have some of the basic knowledge, skills and aptitude to make the leap without too much angst. |
How hard can it be?
We've met Finchey for god's sake?! |
I am ex Shackleton, ex Nimrod, got an awful lot of hours on 737's and I have a beard. Looks like I am the ideal chap to operate the R.N.'s P8s. Might have to lie about my age . Just a bit. YS;) |
Agree 2 engines for LRMPA seems to have disadvantages Saying it's a big turboprop with contra rotating props like the Shackletons and some Spitfires makes people more confident then using words like exotic "propfan".. |
Very high speed at height isn't essential for MPA, superior fuel consumption and performance at lower levels are more important.

It depends on the operational requirement. To use the Nimrod figures, it could react and reach a patrol area 1000 miles from base in 3.5 hours. Unrefuelled it could remain there for 4 hours and be relieved by another Nimrod with 6 patrol cycles in 24 hours. A Shackleton, the epitome of low and slow, could reach that patrol area in 6.5 hours and remain on patrol for 2-3 hours and thus need 10-12 patrol cycles and more aircraft and crews to do the job. In addition the Nimrod would only be 3.5 hours late on a datum with the Shackleton nearly double that. It doesn't take a genius to calculate the respective circles of uncertainty. In the Nimrod case it could reach a point on the circumference in 10 minutes. In the Shackleton case in an hour. These are of course extremes and the speed difference between a modern hi-fast or low and not so slow is not as extreme but it points up the need for speed. In the case of SRMP the difference comes down to launch reaction time rather than sheer speed. |

Another reason for a high-flying whisper jet. |

That laser weapons system they were showing firing on an automobile? The comments about it being useful in an urban environment make me suspect SWAT will want to get their hands on some of those babies; furthermore with the plan to set up an infrastructure in the United States to operate drones such as the Reaper, that could make a fantastic assassination tool.

"You have to ask why on earth a P8 (737) was ever considered for this role :ugh:"
because, dear boy , every attempt to design one from scratch leads to a vastly expensive, unaffordable aeroplane the Orion was based on that grotty Electra they operated for a while in the USA If we'd based our on the HS-748 we'd still have some capability rather than a fantastic series of designs that cost us zillions and left us with nothing............ |
1) The P3 is a very, very successful design that is very good at its job - so I'm at a bit of a loss to understand the reference to the Electra.
2) Why should something based on the 748 be any better than an MPA based on the Comet, which led to the highly successful MR1, MR2, and sneaky beaky R1? 3) An off the shelf option would have been better than a "Bungling Baron Mk4" (especially if we could have fitted our own sensor suite), but nothing you've posted suggests that you have clue 1. |
Anyway, given today's posts on the 'More Defence Cuts' thread, shall we just close this thread...?

I wonder why everybody here assumes a new MPA (if ever) will be just for / from the UK, just like it always was. Are you following the news..
AGI News On - ROYAL NAVY HAS JETS HOSTED ABOARD FRENCH AIRCRAFT CARRIER A European MPA/coast guard fleet with 2-3 standardized types/ procedures seems so much more efficient. A few bases around the edges, mixed crews, moving around fleet/crews to where needed most. |
Electra/P-3 yes, I know.... the same relationship as Comet/Nimrod... I don't see why a 748 would be better than a Nimrod, based on an Electra/P3 comparison? Didn't make sense to me....

1) there are no RN jets on the CdeG. The RN doesn't have any flyable carrier jets 2) that news article in the Telegraph said nothing of the kind. It speculated on possible future co-operation over training and maybe use of the two new British carriers |

thats what I think too.. & it won't be a nice sight, not a bang. |

The P3 and Nimrod were good for Europe for the last 50 years.
Not for the next 50. The world has changed too much. That's why Nimrod was scrapped and Dutch P3 sold.. Sad for everyone involved, IMO a radical turnaround long overdue for Europe. A new flexible and efficient platform is expensive but cheaper to operate, lasts for 50 years and has good export potential. http://i191.photobucket.com/albums/z...ceptkeesje.jpg |
are those Twin Mambas hanging off the wings?
|
Cor Blimey...the Nimrod's L & D handling characteristics could be bad enough.....that looks as though some good training on a skid pad would be required before any OCU....Still the pilots' coffee cups could provide some good turn and slip indications...a lot of the time!;)

Just read this article,
It's a good job we have so many ASW assets to call on.......Oh! DEBKAfile, Political Analysis, Espionage, Terrorism, Security |
I think you have underestimated the galley requirements.......

Tourist I think you have underestimated the galley requirements..... I did a generous bathroom in the back enabling crew members to comfortably refresh, and redress themselves during long (refuelled) flights. are those Twin Mambas hanging off the wings? http://i191.photobucket.com/albums/z...g?t=1307980629 |

Just how quiet are these fan-jets as far as putting noise into the water. AKAIK the Nimrod was much quieter than the P3 but either could be counter-detected on a sub-sonar array.
|
IC, nice thought. Remind me of what is happening to our Js and why.
|
Mrs D'Sorderlee was less than convinced by the Marshalls plan. She suggested that it probably needed another wing, or it would have really poor handling qualities!
Duncs:ok: |
Duncs, they were probably just sniffing the same glue as these guys.

Definitely designed by a Komittee!

I can imagine that optimizing for low noise goes at the cost of efficiency. I guess it could be introduced as an options on engines if required. A "silent" mode to be selcted by the crew. Different rpm's, blade angles.. http://i191.photobucket.com/albums/z...orResearch.jpg |
An interesting view not shared by either Airbus or Boeing.
Boeing has been collaboratively testing this engine with RR but remains very unconvinced of its future. Boeing has three potential engines at its disposal for its new narrowbody including the current next-generation offerings from CFM and Pratt & Whitney, as well as the Rolls-Royce 133-445kN (30,000-100,000lb) thrust Advance3 future three-shaft Trent powerplant, which is currently in development and slated for a 2017 or 2018 entry into service. Open Rotors: Based on our conversations with engineers and Boeing, we remain highly skeptical of open-rotors. Noise, maintenance, safety, size, weight, dimension of the rotor, application and speed all seem to work against this engine type and nobody we know suggests any different. Even Leahy says the open-rotor Airbus believes in won’t likely be the open-rotor as we know it today. One concept is a shrouded open-rotor (isn’t that essentially the ducted fan?), which to us seems to add more weight and issues than problems it solves. Furthermore, both PW and CFM believe that their new engines will, by 2025, have sufficient gains in fuel burn (typically 1% per year) that consumption will pretty well match that promised by open-rotors without the challenges. And RR says it won’t be ready till at least 2020. Lastly, if cleansheet 737 and A320 replacements slip beyond 2022, Rolls believes an Open Rotor design with gas turbine powered contra-rotating propellors becomes a viable option for the 20,000-35,000lb thrust range likely not available before 2025. Horwood is quick to admit that there are many open questions about the technology which could deliver a 30% improvement in fuel consumption and CO2. |
...and that C130 design didn't have any laser turrets either, so how's that meant to work then?
I like the BV 141 though - getting p****d and scrawling something as elegant as a duck on LSD is one thing, persuading somebody to build and fly it is taking the joke to a whole new level. |
The Marshall's plan won't survive first contact as they can't even spell sonobuoy. Oh, and as Duncs says, it isnae very aerodynamic!!!

It has occured to me after looking at your latest computer generated mpa pic that you have put your name on the pic, as if you are afraid somebody is going to run with your idea and deprive you of your intelectual property. This suggests to me that rather than doing this as a bit of a running joke that we have been playing along with, you might actually believe that this is something that might parallel reality somewhere other than in your head. Please tell me that you know it is silly? |
On your usual charming form I see Tourist.
