Wing Section Demonstration Model

Zoology

Accession Number: 2016.zoo.24.1-2

Instrument Name: Wing Section Demonstration Model

Description:

This object is a piece of apparatus for investigating air pressure in different locations on a wing. It constitutes two main sections connected by a number of clear plastic tubes. The main section (24.1) consists of a clear acrylic stand that supports two parts of the the instrument. One consists of a plastic tube set vertically with a black stopper in the top. Protruding through the rubber stopper there is a small tube open to the air.

This plastic tube is connected via a rubber tube to a set of eight graduated glass tubes fixed vertically and connected at the bottom by a horizontal plastic attachment. This is the object’s manometer.

Coming from the top of each of the eight glass tubes is a plastic tube. Seven of these connect to metal attachments on a wing-shape model (24.2); the eighth is open to the air. The wing model is made of transparent red plastic and has seven small holes in it. Each hole corresponds to a tube attachment. The wing section is attached to a metal rod so it can be affixed to a stand.

Alternative Name:

Aerofoil or Wing Section Demonstration Model

Primary Materials: Plastic, Glass, Rubber, Metal

Markings:

On the base of the wing-shape model, two embossed stickers are affixed reading: “ZOO . 220″ and “RM 136″. Each of the vertical narrow glass tubes is graduated and marked with “DISPOSABLE”, “PYREX” and “TD 20°C”. Some other writing on these tubes is obscured by the stand and unreadable.

There are no markings on the wing section.

Dimensions (cm):

Stand: 31cm x 16cm x 34.5cm; Wing Section: 28cm x 9cm x 6cm

Function:

This is an apparatus designed to investigate variations in air pressure over the surface of a wing at seven points. The air pressure differences are visualized as changes in height of liquid within the seven attached manometer tubes.

Condition:

Good. The object is very dusty but otherwise intact. The rubber tubing connecting the vertical plastic tube to the manometer tubes is degraded and cracked.

Provenance:

This object was likely made at U of T to mimick the similar instrument made by Philip Harris Ltd. It was collected from the zoology department and appears to have been used as part of a Zoology course numbered ZOO220.
