APRs for different credit scores will vary across lenders. myFICO breaks down its credit scoring and corresponding APRs for a 60-month loan on a new car into six categories. Note how much lower the rate is for borrowers with the highest scores than those with the lowest:
A feathering propeller is a controllable propeller having a mechanism to change the pitch to an angle so that forward aircraft motion produces minimum windmilling effect on a âpower-offâ propeller. Feather propellers must be used on multi-engines to reduce propeller drag to a minimum under engine failure.
We can study the influence of the propeller diameter on efficiency as well as how it depends on flight speed or the density of the air (corresponding to a certain altitude). We learn, that an efficient propeller should have a small power loading per disk area, i.e. a large diameter is required.
