Fuel Flowmeters

A very satisfying result from quite a bit of perseverance resulted in a totally serviceable fuel flowmeter in XL231. The original proved unreliable, sometimes showing odd flow rates. The rate is calculated via 'windmill' transmitters in the fuel line of each engine supply circuit and then calculated and totaled.

Ken Sanderson; aka 'Radio Ken' and his colleague Terry took 3 Fuel Flowmeter computers including XL231's original and made one good one out of the 3. They tested each radio valve and ensured only the good one's were installed in the best unit. Their time and effort has paid off as each one showed the fuel flow rate at engine idle on last Sunday's 'Thunder Day' at the Museum and the totaled amount is also correct on the totaliser gauge next to the flowmeter controller. This was also recently replaced. None of this is required for what we do with XL231 but, we like to keep her as correctly working as she was in RAF service and for historical purposes.

Well done Ken and Terry!

Servicing August 2016

Servicing work on XL231 continues. Sticking gauges, caused by a lack of use are a bit of an irritation and occasionally some of them have to be removed for servicing. The recent one's are the engine oil pressure gauges for No's 1 and No's 2 engines. These are sticking above zero in an un-powered condition and should fall below zero without power so, they have been removed for the internal mechanisms cleaning. A simple enough job to do but one that has to be done carefully. In addition the No2 engine  Kilowatt power meter from the AEO's main panel has been removed due to the glass being loose and jamming the needle. All three gauges have been replaced with serviceable spare units in the meantime.

New Bungs for Lindy!

As time goes on, age and the weather take their toll, especially on the softer items such as weather protection.

One such item we have run out of are some of the 'bungs and blanks', all very necessary to keep the weather, insects and birds out. The bungs simply rot away over time and in some 20+ years the stock of them has been gradually used up.

It was decided that some new one's had to be made as prototypes so, after a sheet of the correct material was kindly donated by Gary Hancock, YAM employee and former Bae Apprentice it was decided that Danielle would have a go at making some.

The end result is pretty good for a first attempt and these are for the Powered Flying Control Air Intakes in the leading edges of the wings.





Any bungs or blanks from any aircraft type can be modified to fit so, anyone with such items lying around please let me know!

Preparation for 7th August 'Thunder Day'

Its been a while since anything was posted on the blog. But, rest assured work has continued on XL231 as usual. Every Sunday and other days.

The Museum's final 'Thunder Day' for this year will be on the 7th August. ALL activities and engine runs  will be on the Museum site. There will be NO taxi runs for this event.

One item of necessity is fire detection so, regular checks are carried out on XL231's engine detection and other zones of the aircraft. Pictured are the individual engine fire warnings during test and the 'attention getter' that was fitted as a modification to ensure the Captain saw any fire warning as it occurred. To operate the relevant fire extinguisher the illuminated button is pressed.

Gulf War Victor pilot reunited with XL231

A surprise visit on Sunday the 24th April brought another ex-Victor K2 pilot Flt Lt Dave Attwood along for a look at XL231.  He didn't seem to be disappointed by what he saw and we thoroughly enjoyed showing the Victor to him once again.

Dave flew Victor's for a considerable time, including Gulf War 1 (Operation Granby) and was on No55 Squadron until the end of Victor operations in October 1993. He delivered XL161 to RAF Lyneham as one of his last duties for fire training purposes and in order to complete 2000 hours on the Victor K2 took some 2+hours to transit from RAF Marham in Norfolk, to RAF Lyneham in Wiltshire!

First Full Engine Runs of 2016

The 3rd April was The Yorkshire Air Museum's 'Thunder Day' with myself not only running my own XL231 along with the teams support but, also being the 'responsible person' in charge of the event.

The event, despite being static engine runs only was extremely successful on visitor attendance and the Bae Nimrod MR2, Douglas DC-3, DeHavilland Devon and Se5 aircraft were also all run successfully.
                                       
                                             
                                         
                     Port engines at high power




The next planned event is on the 7th May. The Victor and Nimrod will be taxied on the airfield parking apron which is 52 acres (yes 52) of concrete! and the Douglas DC-3 will be on the runway for its first high power taxi tests with a current DC-3 pilot at the controls, with myself in the co-pilot's seat.

Compass change for Lindy!

The Smiths Military Flight System (MFS)  Beam compass for the co-pilot's position failed several years ago and as it is 'type specific' for the Victor K2. I found it impossible to locate the correct one.and so I had to replace it with a Vulcan B2 version which is a Type B. The Victor is modified up to Type C. They are externally identical to each other but with some differing operations . I was lucky to be able to finally locate a correct and unused Type C at Newark Aerojumble and so team member Tom Winter (ex-55 Squadron INSTIE) changed it last Sunday and it is fully serviceable and the system fully working.
