SAI KZ-II Trainer
The KZ-II Trainer was ordered by the air force just after World War II from the Danish aircraft manufacturer Kramme & Zeuthen. The air force had to be rebuilt from scratch, and training aircraft had to be purchased. The choice fell on the KZ-II Trainer, when the air force received a lot of Spitfires from the British in weapons aid, you needed a training aircraft that could help the pilots to acquire the skills needed to fly an aircraft where you sit behind the wing as you do on the Spitfire. In KZ-II the instructor sat in the front seat and the student in the back seat. As you can see if you look at it on the ground, it has a side mirror in front so that the instructor could keep an eye on the student. Back then you didn’t have an intercom like you do today, so everything was agreed before the flight, and otherwise the instructor could give hand signals to the student and see the answer in the side mirror. The plane is flown solo from the back seat due to weight and balance and again to teach the student how to sit “behind the wing”. Very few planes are built like this, virtually all planes you sit in front of the wing.
There is no glass around the pilots but is protected behind a small piece of plexiglass, it is very nice on a summer day, but in winter it is really a cold pleasure, you can perhaps imagine how an instructor felt after a working day where he has flown with a group of students, you can therefore see in old photos how the pilots are well wrapped in warm and leather clothing.
Wingspan is 10.2, empty weight is 550 kg. Full load 850 kg. Travel speed 210-220 km/h and maximum speed is 350 km/h. The aircraft is fully aerobatic.
Engine is a 145 horsepower Gipsy Major, MK.10-2
The plane is a metal tube construction that is covered with canvas on which dope is painted, a technique you can also see on other planes like the DC3 on rudder surfaces and the dope technique has also been used on model planes.
There are only 2 flying KZ-IIs left.
The de Havilland Chipmunk is a tandem, two-seat, single-engine trainer aircraft which became the primary training aircraft for the Royal Air Force, Royal Air Force and many other air forces. The Chipmunk was de Havilland Canada’s first post-war project. The prototype flew as early as 1946. The Danish Air Force began to introduce the Chipmunk in 1950 & 1953 as a replacement for the KZ-II. A total of 27 units of the type were purchased. In Denmark, 2,700 military pilots were trained at Chipmunken. Chipmunk was phased out in 1976, when they were all sold at an auction at Værløse Airport. The price varied between DKK 25,000 and DKK 30,000, depending on the condition they were in.
Over 500 of the 1283 Canadian-British-Portuguese-built DHC-1 Chipmunks are still airworthy, with more being restored each year.
Incidentally, it was the type of aircraft Prince Henrik was schooled in and went solo on.
In contrast to the KZ-II, the student sat in front also during solo flight, the instructor sat in the back. Instrumentation front and rear is completely identical. The pilots who were trained at Chipmunk typically had to go on to fly fighters, such as the Gloster Meteor and Hawker Hunter that replaced the Spitfire. The chipmunk is incredibly flexible, this is due, among other things, to the very thin wings.
Is equipped with a Motor is a 145 horsepower Gipsy Major MK.10-2 same motor as in the KZ-II trainer. The span is 10.45 m the length of 7.80 travel speed 190 km/h top altitude 5000 meters flight distance with full refueling 450 km.
Saab T-17 Supporter
The T-17 SAAB Supporter is the newest aircraft in the group that is still in use in the air force. Built in Sweden in Malmö, by Malmö flyindustri. Here the pilots sit next to each other, and because of where the wing is positioned, have a very good overview of what is going on on the ground. The T-17 has, among other things, been used for speed checks, perhaps on the motorway you can still see a yellow T as the start and a kilometer further on a new T where the measurement stopped.
There may be some here who remember the civil war in Ethiopia Biafra, here von Rosen joined the Swedish Red Cross ambulance mission. He also repeatedly flew victims off the battlefield in extremely dangerous conditions. Here he had some T-17 converted so that it could have rocket guidance and bombs on the wings. The pilot Carl Gustav von rosen was also the nephew of Carin Göring, wife of Hermann Göring.
The T-17 Supporter was purchased to replace the Chipmunk. 32 aircraft were purchased, which were delivered from autumn 1975.
Now you might think that the Swedish Air Force would use this aircraft itself, but the choice was the English Bulldog.
If you look at the tail plane, you can see that it sits higher than the other two planes, the reason being that you would avoid damage to the tail if you had to use a loosely laid runway.
The main plane swipes forward a little, this is to be able to fly at low speed without stalling.
There can be 3 people in the plane, as there is a small space behind the pilots where there is a seat.
Length: 7.00 m. Height: 2.60 m. Span: 8.85 m. Weight: 646 kg. Speed: 208 km/h. Range: 700 km. Engine type: Lycoming O-360.
Extra-400 (Support aircraft)
Used by Danish Military Historic flight as an support aircraft to carry mechanics. spare parts and other airshow crew.
The Extra EA-400 is a six-seat, single-engined, high-wing monoplane produced by Extra Flugzeugbau GmbH. The EA-400 is powered by a liquid-cooled Continental Voyager turbocharged piston engine.
The optional weather radar pod is blended into the left wing tip. All Extra 400 aircraft have been retrofitted with the flight into known icing conditions modification. Deicing equipment consists of Teflon boots, a heated propeller, a heated windscreen for the pilot side, dual heated pitot ports, and a heated stall sensor connected to the autopilot. The deicing equipment is powered by a pair of large alternators (100 and 85 amps) that also feed the AC compressor located in the tail.
The cockpit has good forward and lateral visibility. Avionics are conventional with a full set of instruments for each of the two crew and a central stack. STCs for upgrades to modern GPS navigators and “glass cockpit” displays are available, but the only autopilot certified is the STEC 55X.
An improved propeller with the “b” type blades is available from MT-Propeller under FAA Form 337 Major Modification. It increases climb performance and cruise speed. Time to climb to FL200 is 20 minutes and cruise speed at 75% power ranges from 200 kn (370 km/h) at 16’000 ft to a maximum of 220 kn (410 km/h) at FL 250 (at MTOW and under ISA conditions).
The passenger cabin is air-conditioned and offers four seats in a club arrangement with a folding table. It is similar in size to that of the smaller jets such as the Eclipse 550.
The Extra 400 was costly to manufacture, requiring 16’000 hours of labor, and carried a price tag of $1 million. Only 27 aircraft were built before the company ran into financial trouble.
