Wing Section Demonstration Model
Accession Number: 2016.zoo.24.1-2
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.

Primary Materials: Plastic, Glass, Rubber, Metal
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.
Stand: 31cm x 16cm x 34.5cm; Wing Section: 28cm x 9cm x 6cm
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.
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.

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.
