Bristol Engine Manifold (pg1 Pwr)


Here we have a carburettor
manifold from a
Bristol Mercury or
Pegasus.
It goes between the Hobson carb and
supercharger
part number FB 60534 D9762
The Mercury's smaller size was aimed at fighter use,
and it powered the Gloster Gauntlet
and its successor, the Gloster
Gladiator It was intended that the larger Pegasus
would be for bombers, but as the power ratings of both
engines rose the Mercury found itself being used in almost
all roles. Perhaps its most famous use was in a twin-engine
light bomber, the Bristol Blenheim.

Coffman Starter (pg1 pwr)
A Coffman
starter fitted to a Spitfire

A number of methods have been devised
to cause an internal combustion piston engine to turn over
during the starting process, the most common being manual
cranking and electric starter motors. Another method
involves the use of a special cartridge that is generally
similar to a firearm cartridge (minus the projectile, of
course.) The Coffman cartridge system was one of the most
common brands, entering the market in the mid-1930s; another
was the Breeze cartridge system, which was produced under
Coffman patents.
The cartridge starter offers advantages in certain
situations, particularly in aircraft applications. For one
thing, unlike the business of starting by manually spinning
the propeller, a pilot can operate a cartridge starter
single-handedly from within the cockpit. A disadvantage is
that a supply of special cartridges must be carried, one for
each attempt to start the engine.

RAF RCAF (MERLIN ENGINE) RADIATOR SHUTTER THERMO SWITCH (pg1 Pwr)
LANCASTER BOMBER
MERLIN ENGINE RADIATOR SHUTTER
THERMO SWITCH. THIS SWITCH WAS REMOVED FROM LANCASTER BOMBER
FM 215 AS TIME EXPIRED OCT 26/1959.
Superb item with great
provenance, connection to both Merlin and Lancaster. A very
rare event is to have a picture of the actual aircraft a
part has been removed from, the part was almost certainly in
situ when this picture was taken of
Lancaster FM 215.

History of
Lancaster FM 215
TOS 21.8.45 in RCAF; was
the 4th. Converted by Avro Canada to Mk.10P; issued to
#408(P) Squadron with code 'MN215'; did extensive test on
SHORAN; was used for short time at Winnipeg as a SAR
aircraft with #111 Composite Unit about Aug. 1959; SOC
28.9.62

Oil Heater A/M 5A/2048
220 Volt oil heater. It has a nice A/M crown.
I can only assume this is for preheating oil in big aero
engines. Looks serviceable.

Hobson Throttle Housing
This is a really nice Hobson throttle housing. Its in mint condition and a really nice
display item. This belongs to a Mighty Centaurus engine
which powered the awesome Hawker Tempest. Basically the
piston aero engine developed to the Max. I believe the
Centaurus developed over 3000 BHP and you can tell the
amount of 100 Octane Petrol it needed by the size of this
throttle housing. It contains a huge butterfly valve.

Spit Flips
V1


 |
Pulse Jet Model(pg1 pwr)

Here
we have a pulsejet engine, designed and built by one of my
suppliers. Use to power the V1 flying Bomb, better know as
the doodle bug. Shooting down one of these could prove
extremely hazardous and a technique was developed to flip
the V1 over using the fighters wing . The giro was
destabilised and the bomb crashed.
- Combustion chamber is
from 2mm stainless steel
- Valve plate to which the
valve is attached is alloy
- valve is from 0.005 in
blue spring steel
- Thrust tube chromed and
painted (VHT) mild steel
- Inlet venturi mild steel (VHT)
- Fuel / gas jet alloy
- Valve retaining bolt
stainless
- Fitted with conventional
automotive spark plug
- Overall length 780mm (30")
- Total weight 800g
Starting is fairly
straight forward.
It is extremely loud and so
ear protection is recommended if you intend to run this
model.
- Connect gas / fuel pipe
to fuel jet pipe.
- Connect ignition source
to spark plug.
- Start ignition
(switched off after engine starts)
- Direct stream of air
through front of engine
- Turn on fuel supply
- Once engine is running
steadily (usually after 5 or 10 secs) turn off air and
ignition.
- The ignighter for
starting the pulse jet is included.
As this
unit is home made it is intended for display use only, if
you run the engine you do so entirely at your own risk.

Merlin/Meteor Engine(pg1 pwr) Meteor engines are basically Merlin
engines converted for tank use. They are not supercharged.
They can have Merlin exhaust stubs bolted on and some
people who have these mounted on trailers and run them at
aviation events. They sound just the same as a Merlin
.
Can be mounted on a
trailer and run with a few ancillaries just add a fuel tank,
"Large" these 27 litre monsters can consume a gallon of
petrol a minute. You need an oil tank a radiator and off you
go. Unlike the Merlin fitted to aircraft this engine will
run happily without the need to apply a load. All the
Merlin's you see for static running require some sort of cut
down prop as they do not run well with a load.
They are awesome, the first time one
of these beasts fired up next to me I jumped out of my skin.
Once you get used to it these engines have a presence they
ooze roar power and sound just the same as a Merlin "sweet"

Merlin Exhaust Stub (pg1 pwr)
This is an exhaust stub for a
Merlin. Its in pretty poor condition due to corrosion but
could make a nice display item and is relatively easy to
restore to static condition with some metal filler and some
patience. Not sure which aircraft I think more likely
Mosquito or Lancaster than Spitfire which generally had
shorter stubs.

A mint condition functioning
K Gass primer. Situated in the Cockpit used for priming big
Piston engines for starting. This type of K Gass was used on
the later Generation of engines such as the Rolls
Royce Griffon, a 36 Litre replacement for the Merlin. Also
fitted in the Tempest and Sea Fury using Centaurus engines.
Basically anything with a Big Piston engine over 30 Ltrs.

This belongs
in the instruments section as it is closely related to RPM
indicator's listed in these pages. |
RPM Counter drive(pg10 ins)
This is in superb boxed
serviceable condition (subject to required check's and
permits only opened for the picture and immediately
resealed. These drives were connected to the Merlin by the
normal direct drive cable that powered the
mechanical Rev counters .It generates an electric current
and power's the electrical type RPM indicator. This
type of indicator was used where it was impractical to use
direct drive cable's. They were used in all Mk's of
Lancaster's and many other Bombers where the cockpit or
engineers panel was far remote from the engine. It was
actually used to power the RPM gauge in the rear cockpit of
the very rare two seat Spitfire's. These do appear from time
to time but never in this condition, this should end up on a
flying aircraft.

Merlin Piston 1 (pg1 Pwr)
The
short Merlin piston was introduced sometime around the beginning
of 1943 to combat skirt failures caused by cracking,
it was found that this part of the piston was not needed
and all subsequent engines had short pistons with the
exception of the Meteor.
Merlin are forged, looking
inside the piston it is easy to tell Merlin and Meteor
ones apart, as Meteors were cast.

MK XX Merlin Piston 1 (pg1 Pwr)

Above a Merlin XX Note
the skirted Pistons.
The Merlin XX which ran on 100 octane fuel. This allowed
it to be run at higher manifold pressures, which were
achieved by increasing the "boost" from the supercharger.
The result was that the engine delivered 1,300 hp
(970 kW). Another improvement made to the XX and future
Merlin variants was a redesign of the cooling system to
work using a 70/30% water/glycol mix rather than the 100%
glycol of the Merlin I, II and III series. This allowed
the engines to run some 70 degrees cooler, substantially
improving engine life and reliability. This also removed a
potential fire hazard from Merlin powered aircraft, as
pure ethylene-glycol is a flammable liquid
