Popis: | 1. Guide-vane units of the types tested can increase the throw of a jet created by a propellerby a factor of 1.3–1.8 for the same drive power. The use of distributor units to untwist the jet is inadvisable for economic and health reasons. 2. To analyze a jet untwisted by guide-vane units we can use the equation for untwisted jets with the coefficients α. 3. For open-pit ventilators of limited size, it is advisable to get the required throw of the jet by increasing the number of guide vanes in the unit and reducing their width. |
