A couple years ago, Sensenich introduced a ground adjustable propeller that includes alignment pins to easily set the blades at the same pitch setting. It took so long as it was difficult to get all the blades three, in that case set the same way using a protractor while fighting to keep the blade from moving when the bolts were tightened. That can be played for years and many thousands of dollars. Aero-TV: Sensenich Technologies - ‘Propping’ Up The UAV Industry I finally concluded that what I wanted was a propeller that I could set for cruise when I wanted to get up and go places and, reasonably easily, change to a climb setting when I wanted to operate in the back country. Those are adjustable in-flight but are quite expensive, heavy, and require the appropriate engine configuration as they use pressurized engine oil for operation. A nice solution would be a constant speed propeller. That means that it is kinda like flying around in high gear. It is a pretty nice Catto prop but is more of a cruise prop. The most significant limitation has been my propeller. However my little Vans RV-4 sure does a great job with it.

To my knowledge Sensenich is the only manufacturer for which we have been able to correlate serial numbers with approximate date of manufacture.ĭrawing No. This is a fairly large page it may be easier to locate your prop by using the search or find tools of your web browser. Locate the drawing number in the left column then read across to locate the aircraft and engine combination the prop was designed to be used on. The table below is arranged in drawing number order.

There are a few exceptions to this logic. The logic of the drawing number sequence is the first number is the length in inches, the middle letters designate the engine and the final digits are the pitch.įor example, a 72CK is a 72 inch prop for a Continental engine and has a pitch of 44 inches. Sensenich props are stamped with a number known as a drawing or design number. A number of propellers were built in the early forties under military contract using the year of contract as the first digits of the design number.
