Abstract
This study attempted to provide a foundation of basic information which will be useful in designing air curtain tractor cabs.The main purpose of this investigation was to determine the relationships involved by studying the effect of a crosswind on an air curtain.This information will provide answers to questions concerning the feasibility of the air curtain tractor cab.Another purpose of this investigation was to determine what effect, if any, a curtain of air will have on noise. As a result of these findings, recommendations will be made concerning areas of needed future research. Finally, a prototype design of an air curtain tractor will be proposed.
The study concludes that the application of an air curtain for a tractor to protect the operator appears feasible. It will deflect winds of up to 20 mph from the operator.Based on previous findings, the determined design air curtain velocities are more than enough to keep rain, dust, insects, etc. from penetrating the curtain.It will not reduce tractor noise, but if a suitable fan system can be designed, the air curtain will at least not increase the existing noise levels.It is evident that more research is needed.
