Something to think about on a rainy afternoon!
Our goal is to:
Prevent bugs from accumalating on the bulk head
Minimize noise in the trucks cab
Increase fuel economy
and not creating other problems (like pulling road dirt into the area)
When designing or adapting devices it is important to have a feel for what we are trying to achieve.
I started off this thread talking about watching ducks in flight.
Have you used an umbrella in high winds... of course you have:
And had the wind fill the inside of it and try to drag you like a parachute.
The space between the trucks cab and the cabover on our truck camper is like the inside of the umbrella... it catches the wind and rain.
When the umbrella fills with the wind and rain it pulls and tugs... the edges of the umbrella vibrate. (That action also accounts for the noise inside the truck).
What did you do with the umbrella, how did you solve the problem?
You put the top of the umbrella into the wind so that the wind would move around and off the sides... (and you were like the bulkhead) the rain and wind no longer hitting you.
The rain drops in the umbrella... are like the bugs would be on the bulkhead.
How many tiny umbrellas (like in tropical drinks) would it take to solve the problem?
Just something for you to consider as you ponder our project. Our project... yes, it is something that many have worked on during my 10 years on the forum.
Thanks for putting up with me
