W.B (Bill) Barber's Snark

There is a lack of information on the web of the New Zealand indigenous microlight, the Snark. In gathering information for my own page on the Snark (located here , designer Bill Barber supplied me with a fairly full set of specifications, and offered me some of his own pictures to use. Since my standard page layout doesn't include all these details and there is a such a lack of information on the web, I thought it would be useful to add a new page. I hope this will answer any questions you may have about the Snark - otherwise Bill's address is at the bottom of the page.

SNARK HA1 ZK-FOU (now deregistered)
Single seat, all composite, mid engine, shaft driven prop behind the tail group, Rotax 503 powered.
This aircraft was never flown, except for a few short "hops", due to an attack of extreme cowardice on the part of the builder. It has been deregistered, but will be revisited sometime.

The prototype and "plug" for what has become the HA3. Designed as a two place micro., but registered and used as a single place. Will be redesignated as a two place microlight, and after inspection will be become an HA2-B.
Welded tube frame, composite wing structure and tail boom, fabric covered wing and tail surfaces. Has a large wing area and very low stall speed, somewhat less than 20 MPH.
Rotax 503 powered.

Same general appearance as FYE, but is all composite construction, with a different wing. Wing has less area, higher AR., a laminar section, and has full span "flaperons".
This wing has less washout than intended, .75 of a degree, and will drop a wing at stall. Subsequent examples have more washout.
Powered by a Suzuki G13 motor.

SNARK HA3 ZK-PIE #002 D Laing Dunedin
Supplied in pieces to David Laing. Is identical to JEK except that it has separate flaps and ailerons, and the wing has 2 degrees of washout. In view of this, suggest that it be called an HA3-B.
Suzuki G13 motor.

Identical in all respects to PIE, except has Suzuki G13 GTI motor.

Note: Before anybody asks, the designation "HA" is the result of a pathetic joke, which I have absolutely no intention of repeating to anyone, except to point out that it does not refer to "Horses Arse"!

Main Gear LegsUD Carbon and Kevlar.

Resin used : Structural components - ADR 240 with ADH 160 / 162

Wing and control surface skins are vacuum bagged and oven cured.
All components are oven post cured, to a cure schedule appropriate to the resin system
being used.

Any future kit production will be based on the machine now under construction, ie:

Engine bay will be widened slightly to accomodate Rotax 912, or Jabiru etc.
Flaps will be slotted instead of plain as at present.
There will be some weight saving made in the airframe.

These changes should result in increased performance.
