Hi,

Van den Berg Staalvogel =

Hans van den Berg uit Baambrugge heeft vijf(!) maal een vliegtuig gebouwd, vanaf 1962 bouwde hij drie toestellen die echter geen van alle gevlogen hebben.

Zijn vierde project (Staalvogel 4) was in 1968 klaar en kwam op 5 juli van dat jaar inderdaad van de grond: "Het mini-vliegtuig, met vleugels van

boekbinderslinnen (Waterlooplein), met een scootervoorwiel als neuswiel, twee motorfietswielen als landingsgestel, een automotor en hier en daar wat

elektrapijp verhief zich, bestuurd door Skylight-directeur Johan Daams, boven het Hilversumse vliegveld ongeveer 25 cm van de grond".

Grootste hoogte die later op die dag nog bereikt werd, was ongeveer 8 meter.

Commentaar van Daams: "Werkelijk, met dit vliegtuigje tart je de wetenschap!"

Op dezelfde dag vloog ook de bouwer zèlf met zijn creatie, maar hij schrok zó van de bereikte hoogte dat hij de stick naar voren duwde en het toestel

tegen de grond vloog. Het is niet meer gerepareerd.

Later bouwde hij de Staalvogel 5, de PH-BER, en daarbij zouden nog delen van de Staalvogel 4 gebruikt zijn.

Hans van den Berg from Baambrugge has built an airplane five(!) times, from 1962 he built three aircraft, none of which flew.

His fourth project (Staalvogel 4) was finished in 1968 and was indeed launched on July 5 of that year: "The mini-plane, with wings made of bookbinder's linen (Waterlooplein), with a scooter front wheel as a nose wheel, two motorcycle wheels as landing gear, a car engine and some electrical pipes here and there, controlled by Skylight director Johan Daams, rose above the Hilversum airport about 25 cm from the ground."

The greatest height reached later that day was approximately 8 meters.

Comment from Daams: "Really, with this airplane you defy science!"

On the same day, the builder himself also flew his creation, but he was so shocked by the height reached that he pushed the stick forward and the aircraft flew into the ground. It is no longer repaired

Hi,

found this from a dutch forum.

Titled "Hans van den Berg & the steel bird"

[Luxonardo]

Am I the only one who thinks that the Staalvogel 4 looks like a skeleton Cessna 172?

On September 13, 1969, the gentleman flew van der Ham unintentionally for the first time with a by Cor Dijkman Dulkes built plane, powered by a DAF engine. It was in the intention to take some taxi tests on the beach at Wijk aan Zee with the “ Bravo ”, on which “ PH-COR ” was painted illegally. It plane came off the beach and the kite dared not land on the busy beach and decided to set course for the Rotterdam airport, where he landed on the grass track. The result was a lot of media attention and a fine!

This was the first step after the Second World War to amateur construction in our country.



In the early years ’ 70 was a number persons engaged in autogyros in our country and during the exhibition Rotorix of the Aircraft Engineering
Study association Sipke Wynia in 1971 the idea for the founding of the Dutch Association of Amateur Aircraft builders, which on April 23, 1971
became a fact.

Before the War there were already various devices built in our country such as the Pou-du-Ciel and at the time of the establishment of the NVAV in 1971, there were three projects under development: the Steel Bird PH-BER (four different models) by Hans van den Berg, Dijkhastar II PH-COR by Cor Dijkman Dulkes and the gyrocopter Verlaan Boomerang PH-VER van Carel Delayed.

I came across this part from a different article on the same website, apparently it was gonna be based on an RC aircraft.

There are some entries on the NVAV website that have little to no information about them.

Hi,

Here's an article about a V-20 (a Dutch glider that was built in 1939) that was piloted by a member of the Utrecht Royal Dutch Aviation Association and was a representative of Gelderland.

Thank you,but here we speak about Post WWII period.

Buijster gyrocopter 1994

Sjaak Buijster heeft zelf een door een Trabant-motor aangedreven gyrocopter ontworpen. De bouw werd in 1994 gestart en de motor heeft met de eveneens zelfgebouwde propeller al proefgedraaid op een tijdelijke, wèl op een gyrocopter lijkende, constructie.

Streefjaar voor de eerste vluchten was het jaar 2000.

Google translate,

Buijster gyrocopter 1994

Sjaak Buijster himself designed a gyrocopter powered by a Trabant engine. Construction started in 1994 and the engine has already been tested with the propeller, which was also self-built, on a temporary construction that resembles a gyrocopter.

The target year for the first flights was the year 2000.

Thank you, I promise to look next time when looking at the forums.

Anyways, here's a 1981 article about Gerrit te Pas helicopter

Translation by google

From one of our reporters
HALLE, Thursday Pilot's license or not, Gerrit te Pas (40) from Halle in Gelderland will and must take to the air. He has to leave a complete self-constructed helicopter on the ground due to lack of flight training. He looked for a solution and found it in another flying principle: the gyrocopter.
We do not have a pilot certificate for such aircraft, so the Achterhoeker can fulfill an old childhood dream. It is a hobby that I completely agree with. Gerrit te Pas in his self-built helicopter, although he is not allowed to take to the air. He will use his self-built gyrocopter for this. Our country does not have a pilot certificate for this.
live it out,” he says.
The gyrocopter is propelled by a propeller, driven by a 2300 cc VW engine. The aircraft becomes airborne by means of a rotor, which rotates at forward speed.
Te Pas will spend his holiday at Lelystad airport to master this type of aircraft, which is new to our country.
At the end of May, his gyrocopter can be seen at an exhibition of the Dutch Association of Amateur Aircraft Builders (NVAV) in Lelystad.

a Limburgs dagblad article about the Hans Den Berg Staalvogel.

The Staalvogel Article

 

[Luxonardo]

Found more articles/photos about the Staalvogel and Hans Van den Berg, I think that I've found all 5 Staalvogels.

I would also like to note that "BER" in the registration "PH-BER" is in reference to his name.

Conijn 2000

Hoewel zeker geen kandidaat voor het N.L.R. toch vermeldenswaard. De kunstenaar Joost Conijn bouwde behalve een houten auto ook een vliegtuig waarmee hij inderdaad in de woestijn in Marokko gevlogen heeft.

Later herhaalde hij dat nog eens in Tsjechië met een bouwsel waarop een Tsjechisch kenmerk OK-KUL 09 was aangebracht. Hiermee crashte hij.

Google translate,

Conijn 2000

Although certainly not a candidate for the N.L.R. still worth mentioning. In addition to a wooden car, the artist Joost Conijn also built an airplane with which he actually flew in the desert in Morocco.

He later repeated this in the Czech Republic with a building on which the Czech mark OK-KUL 09 was applied. With this he crashed.

 

[Luxonardo]

Hans van den Berg himself is overall an interesting engineer as he built a steam vehicle and even a steam rocket before he began to build the Staalvogel.
