Pictures of HXb

This is how the HXc looks like in the museum.

Gallery of Ronaldo Jones and Chantal

I have to thank Ronaldo Jones and his wife Chantal for visiting "Museo Nacional de Aeronáutica" in Argentina (near Buenos Aires) especially for me. Ronaldo is of origin from Argentina, but he now lives in Belgium.

It seems that the museum shows the glider no longer hanging from a ceiling. It makes it possible to walk around and even photograph the inside. Euh .. the tire is really not very honourable to the glider, but ... it is as low-budget as the glider itself. ;^)

The plate next to the glider. Translation (by Fernando Sairez): "HXB Piernifero II Origin: Argentina The first HXa (Piernifero I) was built in the beginning of the 50's by a reduced number of members of the Cordoba Glider Club. The first trials were made on 7th February 1953 at the "Pampa de Olaen". The flight activity was methodic and productive, allowing to confirm the design objectives that, from any point of view, results in an outstanding stability. The turning radius resulted very small, it practically turned on the wing tip. As a result of the flights, it was determined that wing loading was to be reduced, in order to be able to take-off by running against a slow wind; so Dr. Horten designed the HXb of 10 meters span instead of the 7.5 meters of the HXa. Due to bad quality of some of the plywood sheets used in the active leading edge covering, this second Piernifero was not flown. Drawing: rough scheme of H-Xb, MIXED with a side view of the H-XC !!!"

I guess that it is due to the use of the plexi-nose as support that the plexi no longer fits its place. You can see that the top of the "cockpit" is removable. The Horten Hxb has two main parts (both wing) and a few parts to be placed in the middle (plexi in front, canopy and wooden top of cockpit). I guess that is all. To me it looks like a quickly assembled glider.

In this view you can see a bit through the canopy. I still have a question about one part there. Later more about that. You can see the part of the top of the cockpit that is removable.

This picture is on its side. It is a view inside the canopy from the front of the canopy. You can see the end of the bottom hole. Also, you can see that the tubes in which the pilot was placed (and probably also attached with belts) are removed. The tubes were rotatable.

View from inside the cockpit. You see the tube which connects the top of both wings.

Here we look through the front plexi from below. You see the canopy and ... the stick. Note the angles of the pushing rods! Not at 45° from axis which runs from front to rear! More about that in the details page.

You see the plates (left) which connect the wings bottoms. The lighter brown part is probably the removable part of the top of the cockpit. The metal plates at the top and bottom are the placed where the "pilot-holder" was fixed. This pilot holder was a set of tubes in which the pilot slipped through and was attached to by harness-belts.

Elevon. You see that it is not a gap-less hinge.

Bottomview of elevon. You can clearly see that the HXb doens't have a Frise-elevon. The HXa had. More info in the details page.

Elevon top

View inside the ribs. You see the structure inside the leading edge. Two plates with weight-reducing holes are placed at a angle to form the rib-shape before the spar. They are reinforced by two slender alu(?) plates with reducing holes. One for the top, one for the bottom. More important to me: You see that the pushrod makes a angle. At the forth rib in this picture there must be some kind of pushrod-hinge. I hope to find more info about it.

A view of the leading edge near the elevon. You see that the plywood is placed rib by rib. Today there are systems which makes this not needed.

View from between the ribs towards the canopy. Topwing-connection, canopy, "pilot-holder"-mountingplates and wing-bottom-connection (left- bottom) visible.

This is the view between those strange parts (which I like to know their function, see here to see which two rectangular parts I mean). Pushrod, stick-ball and front plexi visible. Hihi, the tire too. And ... it that some kind of glue to put the plexiparts together ... or ... is it birdsh*t?

Another view from between the ribs towards the cockpit and stick.

Both pushrods and the "stick-ball".

Here it is again visible that the pushrods are not angled like I first expected. Go see the details page, where I explain the reason why.

The stick is nothing more than a ball! There is no hinge at the bottom of the stick like usual. I ask myself: "How does it stay on its place? I don't see any other means to keep the pushrods in their place?"

Aaaaaaah. Looking at it makes me dream away.

 

Gallery of Fernando Sairez

I have to thank Fernando Sairez for giving me these pictures. The first two are rare pictures of the construction of the Horten Hxa. The latter are pictures from the HXb exposed at "Museo Nacional de Aeronáutica" in Argentina (near Buenos Aires).

The comments are by Fernando sairez.

Barely visible is the union of the two pushrods that make the "Vee". The union is made with a pin bolt capped with a black ball that was to be grabbed by the pilot's hand for control.

HXb pilot "cockpit": to the left is a steel plate with 3 holes for the pilot's "hexagon" (3 positions?); also visible upper structural compression tube and underside dis-assembling lugs.

HXb pilot hexagonal harness in position: are visible two small levers to retract the plunger pins and get out of the craft

View of the port elevon that has fallen due to gravity, closing its lower gap. You must see that it's very different from the elevons in the HXa glider. The HXb elevons are said to take advantage of the bell distribution to overcome the adverse yaw. (this photo is taken from the left tip of the aircraft towards the center)

The same elevon as before, but fixed neutral with a metal clip: the lower gap is a big one.

View of starboard wing from the root to the tip: the push-rod "Vee" ends near a wooden lug that allows the outer push-rod to slide.

I have to thank Philippe Vigneron for giving me these pictures. All are taken at "Museo Nacional de Aeronáutica" near Buenos Aires, Argentina.

 

HXb and IA 41 "Urubu"

HXb on display at ceiling

One of the rare pictures of the pilot-figure in the glider. Note: the position of the doll is not right. Its legs should be bended and the body should be less flat.

I was contacted by

Departamento de Aeronautica
Facultad de Ciencias Exactas, Fisicas y Naturales
Universidad Nacional de Cordoba
Argentina

They gave me plenty of pictures of the Horten HXb and the permission to place them in my site. Many, many thanks!

If you can add some data about these pictures (like the names of the people on the pictures), feel free to contact me. I will place the data online and add you as source.
