Drag Force
Product Code : EL-AEFT-11259
Quick Answer: The Drag Force experiment module is a duct with a transparent front and rear, fitted with a Pitot tube for wake traverse and a mass balance for direct drag measurement. It comes with three models of the same frontal area: a cylinder, a flat plate and a symmetrical aerofoil.

Key Features
- Duct with transparent front and rear; scales printed on the front for positioning parts
- Pitot tube and mass balance mounted outside the duct for wake traverse and direct drag readings
- Three models of equal frontal area: cylinder, flat plate and symmetrical aerofoil
- Cylinder has a protractor and a pressure tapping in its outer wall
- Balance arms rotate clear of the duct so the cylinder can be fitted between the duct walls for pressure distribution work
- Pitot tube and cylinder tapping connect to the manometer (ancillary) by flexible tubes with quick-release couplings

About This Product
This module lets a class measure drag in two independent ways and compare the results: directly on a balance, and indirectly from the velocity loss in the wake behind the model. Because the three shapes share one frontal area, differences in drag come from shape alone, and the cylinder can also be turned to map pressure around its surface.
Frequently Asked Questions
Which models come with the Drag Force module?
Three models with the same frontal area: a cylinder with a protractor and a pressure tapping in its outer wall, a flat plate, and a symmetrical aerofoil.
Is a manometer included with the Drag Force module?
No. The manometer is an ancillary; the Pitot tube and cylinder tapping connect to it through flexible tubes with quick-release couplings.
