Cougar model in 1/32 scale Matchbox / Revell Puma Helicopter Conversion by Meindert de Vreeze
Cougar model in 1/32 scale Matchbox / Revell Puma Helicopter Conversion
AS 532 U2 Cougar Mk II is operated by the Dutch Air Force [KLu]
on behalf on the Dutch Air Mobile Army Brigade. It seemed very nice to
have a large 1/32 model of this helicopter in the collection and as Matchbox
issued a 1/32 Puma kit (later improved and issued by Revell), a conversion
project was started.
The Eurocopter Cougar AS 532 helicopter is derived from the Super Puma and in fact the Puma helicopter developed by Aerospatiale and Westland emerging the mid nineteen-sixties. The original Puma helicopter designated SA 330 was a tactical transport helicopter and the first production Puma flew in 1968. It was and still is used by many air forces and by civil operators. It has a crew of 2 pilots and a navigator and a cabin for maximum of 16-20 troops or passengers. The Puma has a maximum take off weight of 6400 kg with two Turbomeca Turmo engines. The rotor has a diameter of 15 meters and its overall length with rotors turning is 18.15 m. Fuselage length is 14.06 m and its maximum speed about 280 km/hour at sealevel.
The Super Puma
twin turbine medium lift helicopter was extensively modified from the original
Puma. The Super Puma AS 332 was a longer and upgraded version of the Puma,
the type being continually improved and enlarged. It had a larger cabin
and more powerfull engines.
The latest military variant of the Super Puma is called the Cougar. It has even more modifications as compared to the Super Puma. First flight of the Cougar was in Februari 1987. The new European Eurocopter organisation is now the manufacturer.
532 U2 Cougar Mk II is an unarmed tactical military transport helicopter
and it is also used by the Royal Netherlands Air Force on behalf on the Air Mobile
Army Brigade. It is even longer than the Super Puma as the fairing between
the aft cabin and tailboom is a bit longer and made of composites. The
latest Cougars got an improved rotor system with larger diameter blades
and a new rotorhead that incorporates some lessons learned from the NH90
helicopter currently being developed (a never ending project....) . It
also has a small weather radar in the longer nose.
AS 532 U2 Cougar technical data:
Note for 1/72
builders: the 1/72 Italeri/Revell kit is fine for a Super Puma and can
be used as a basis for a AS 532 Cougar with the exception of the rear composite
The kit in
obtained the Matchbox moulds and issued in 1993 the Puma as kit
The 1/32 scale conversion project for the Dutch AS 532 Cougar can use either of these Puma kits. It is noted that any of the Revell kits are recommended as you get some finer updated parts and the intake filters.
To extend the
fuselage and rotor blade diameter however, two Puma kits are required to
save some work. I obtained an old Matchbox Puma and a newer Revell #04499
kit to be used in the conversion Cougar project.
The Royal Netherlands AF Cougar can be made as in model in various configurations.
It is flown with two types of main gear interchangeable sponsons: a smaller type and a larger type (note that the larger one is very different than the ones in the BGS kit).
Also, various engine exhaust configurations are seen with sometimes a JDD, jet diffusion devices which is in fact a infrared protection fairing. There are also various other changes, so scratch modelling will be required any way.
It was decided to make a Dutch Cougar
as flown during flying qualification tests from Royal Netherlands Navy assault/ transport
ship Hr.Ms. Rotterdam in 2005.
Also, a lot of folding blade test
were done on deck to check handling and behaviour. This is an interesting
setting, and for me as a modeller: it would save a lot of space later on
in the model display cabinet!
|It is noted
first that a description to all the bits and pieces regarding the conversion
is nearly impossible. Many many parts were made based on pictures, drawings,
estimates and a lot of scratch building.
About 50% of the parts could be used in some way of the Puma kits, the rest was scratch. This modelling report can only show some items. But enjoy!
Besides the lengthening, the Dutch
Cougar has different windows. Cutting out the various windows and giving
them the correct size should now be done and is obviously important. The
dimensions of the various windows were determined from the drawing and
checking also with the 1/72 Italeri kit. Filing, sanding and cutting was
now done at the various fuselage parts. The various windows have raised
edges. These were made with metal wire.
"Left overs" after cutting...
The extened fuselage was now first constructed. As there are two large side doors, adding all the internal details within the cabin is not required at this stage.
The extended floor was added, and also a roof added in the upper cabin from card. Also some details at the fuselage cabin sides were added made from plastic strip.
The Cougar has a different and longer rear cone at the rear fuselage as compared to the (Super) Puma. It is the fairing towards the tail rotor boom that needs another extension to make the composite fairing typical for the later Cougar AS 532 variants. Some Puma parts were used with white plasticcard and sprue for strength (see page 1 for dimensions).
Milliput was required to get a smooth straight cone shape. A lot of work was needed here. The cone shape is rather straight tapered.
Most of the AS 532 Cougars also have an added fairing with a hatch at the lower side of the cone. So does the Dutch Cougar. This was made from straight card.
The longer radar nose was moulded from Milliput. The clear cockpit windows were cut off and are to be added later on after the basic model has been correctly shaped.
The lower cockpit section can be seen here (after main fuselage assembly) with added fairings and various stubs. Quite some work is needed here to get a smooth result.
