Lockheed XV-4 'Hummingbird'
« on: January 30, 2008, 12:23:48 pm »
Lockheed produced several initial designs leading
to the Hummingbird.
One of them was the GL-224-2 concept.
Is there anyone who can help with a decent three view drawing or an
other  illustration about?

The 'X' plane book No.5 -HPM Publications haves an illustration
but in my copy the drawing is almost invisible.

Thanks in advance.

It's almost impossible to see anything but it looks almost identical to GL-224-3 whith less prominent intakes.

While testing the XV-4A (but prior to the XV-4B redesign) Lockheed offered a production variant of the Hummingbird, which is briefly described in Jane's All The World Aircraft, 1964-65.

Attached is a factory model of this production variant (V-4A?). A comparison photo with the VZ-10 (XV-4A) model shows numerous aerodynamic and design improvements.  Among them is the large ventral weapons fairing, shorter tail fin, reduced stabilizer area, extended intakes, different canopy, integrated puffer jets, canted wingtip fairings, tail probe, single VTOL intake doors (instead of split louvers), etc.

Additional info, drawings and data are always welcomed.

  • Beautiful artwork of the Hummingbird when it was still known as the VZ-10 (source: Flying, May 1962)

Have looked through this and some other threads, but couldn't find a better drawing,
so I hope, that this one, though far from being perfect, is just about 8 years late ....   ;)

Drawings here

Hey, nice find gents with the desk-top models and drawings gents!!
Justo Miranda that cut-away drawing of the Hummingbird really emphasised to me the internal volume and weight of the separate lift and propulsion jet arrangement takes up within such a design!!

Tried to clean up the above posted drawing, but without much success. So
I decided to redraw it, but I encountered several uncertainties.
The actual arrangement of the augmentor on the upper side of the
fuselage isn't clear to me, as well, as the position of the bulge at the
fuselage sides, visible on the top view, but not on side view.
If someone has better ideas, just tell us.
And if someone wants to make changes by himself, I've attached the sketch
as pdf-file, suitable to be imported to Inkscape or CorelDraw.
