Hi guys, I've seen some of you calculating forces on flaps before, can someone help me with the numbers for my flaps. (it's been over 30 years since I've had to do this kind of math)
* Flap size approximately 24" wide by 11.5" deep * Hinged at the forward leading edge * Deployed up to 60 degrees to relative airflow. * Pickoff will be ~6" back from hinge (1/2 way back) * Operating arm ~6" long * Torque tube across boat ~ 38" long * Centre pick-off at an arm ~6" long (driven by lever or actuator?) Q1 - what would the force be at the operating point on each flap Q2 - what torque would this be via the 6" arm? Q3 - would this translate to a force double this on the operating arm. Q4 - Has anyone used CF rod as a torque rod? Paul Smith Brisbane, AUSTRALIA pk.sm...@bigpond.net.au http://kr2spacemodulator.blogspot.com/
