Various Dutch Little Known Designers,Aircraft & Projects

NAVO N.A.V.6 Limousine 1920

The Dutch Automobile and Aircraft Company wanted to start an Amsterdam-Berlin service with a self-built aircraft.

Trials at Soesterberg were postponed and ultimately canceled due to repeated engine problems.

The aircraft was also offered to KLM and shortly afterwards the company was closed down due to a lack of resources.

The device was stored in Soesterberg. In 1925, the Maas en Waalsche Bank in Nijmegen inquired about the condition/value of the device.

and the possible demolition value of the aircraft and engine.

The C. LVA answers that the value was nil and at the same time asks whether demolition can proceed.

The aircraft will also have been demolished shortly afterwards.

- Was that any more aircraft designed by this company ?

Flight 1921.

Some information, in Dutch, on that aircraft can be found at https://cuijksarchief.nl/node/228/van-cuijk-monoplane

A relatively good translation of that text seems to be available via https://cuijksarchief-nl.translate....noplane?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en

Navlietra 1935

In November, the municipality of Gouda received the application from ing. Verfuerden for the lease of a plot of more than 10,000 m² along the Nieuwe Vaart.

The “National Aircraft and Transport Equipment Industry” (“Navlietra”) would be established there and, among other things, small sports aircraft would be built there.

About two hundred jobs were provided in addition to engineers, draftsmen and other staff. Nothing more was heard about it.

 
Alsters 1934

In Blerick, a 'young man' first built a hover model of approximately one meter in length. Then a larger (length 3.5 and wingspan 4.5 meters) motorized aircraft that flew (unmanned!) but crashed after the first flight. In Het Vaderland of January 31, 1934, a larger (passenger) aircraft with a 400 hp engine is announced. Heard nothing more about it.

I have posted a photo of the motorized project on the illustration page

 
Albers experimental plane 1928

The press paid attention to this very revolutionary device. It would take off by rotating the upper wing on its axis while flaps in the lower wing would be open and the tail surfaces would be set to the vertical position.

With sufficient height, a normal propeller would then provide the forward speed, the upper wing and tail surfaces would be fixed in normal position. Haven't heard anything else about it yet!

 
Bannet SV.2 1936

On May 22, 1936, the Bannet Aircraft Factory in Zeist submitted a BvL application for this sports and training aircraft to be built.
Factory number B.3 was specified.
The aircraft was designed by Messrs Kelder and Stokfleth, the constructor was Mr Groot who started construction in 1936.

Despite repeated assurances that the drawings and calculations associated with the application would be submitted, this only happened at a slow pace and piecemeal. Moreover, these calculations contained so many errors that the RSL decided to redo all calculations in the form of a study project for new employees.

In 1939 Mr Bannet was advised to withdraw his application. He followed that advice on 27.6.1939 and on 14.7.1939 he was officially informed that the inspection work had been stopped. So it was never completed.

In May 1940 it was still with Mr. Large in Hamerstraat 16, assessed by the occupiers as "Ist noch im bau begriffen".

An extensive article about this project is included in "Dutch Aviation History".

I'm not sure I understand the point of strip-mining Herman Dekker's entire website. But, if you are determined to do it, search his site for your specific subjects so that you can combine the information to add some value.

In this instance, see: https://hdekker.info/DIVERSEN/tcgroot.htm

It also helps to give context and define acronyms used in your clippings and to avoid pointless/confusing translations. To wit:

Vliegtuigenfabriek Bannet = Zeist-based aircraft factory (no "Bannet Aircraft Factory" ever existed).

BvL = Bewijs van Luchtwaardigheid - a Certificate of Airworthiness.

"Factory number" = Fabrieksnummer or construction number; in other words, c/n B.3 was assigned.

"Messrs Kelder and Stokfleth" = J. Kelder and G.H. Stokfleth of the Stichtsch-Gooische Kleine Luchtvaartclub (SGKL) [1]

"Mr. Large" = Seriously? T.C. Groot, the constructor, was also the owner of a lumber yard. [2]

RSL = Rijksstudiedienst voor de Luchtvaart (1919-1937), roughly the 'National Office for the Study of Aviation'.

"Ist noch im bau begriffen" = [German] 'Is still under construction'.

"Dutch Aviation History" = Nederlandse Luchtvaartgeschiedenis

_______________________________

[1] The SGKL was a glider club based at Hilversum (~15 km south of Zeist). Note that 'G.H. Stokfleth' was also the name of a machinery factory (later Stokfleth Machines; now operating under the Stoxon brandname). So, we can't be sure if the firm was offering support for this Bannet project or the G.H. Stokfleth mentioned was the owner (or a scion) with a passion for gliding. As far as I can tell, J. Kelder was a lawyer. So, likely another enthusiastic amateur.

[2] In the link given above, Dekker described that business as "Naaml. Vennootschap HOUTHANDEL voorheen T.C. Groot". So, T.C. Groot had once been the owner of an eponymous business which was now nameless (Naamloos). [Edit: see reply #50] Perhaps that suggests that Groot had fallen on hard times. Or maybe he too was just an aviation enthusiast ... who happened to have easy access to some of the needed raw materials?

In full: "Naamloze Vennootschap HOUTHANDEL voorheen T.C. Groot"
The part in red is a type of public company under Dutch law, akin to the French Societé Anonyme.
The part in blue is the company name - originally just T.C. Groot, then renamed HOUTHANDEL voorheen T.C. Groot, which may have been simply because wood merchant (HOUTHANDELAAR) T.C. Groot sold his business, with the new owners retaining some of the old company name to signal to its customers the renamed company was a continuation of the old company.

I agree.

the cuyck article mentioned that Rethel was sidetracked, but this is wrong. He worked with Messerschmitt on the Bf.109 and afther that was a leiding part in the construction of the Bf.110. Later in the war he was involved with the Me.321 and 323.
