REFLECTOR: Retract Pressures

[Al Gietzen]

(snip): I noted early on that it took an unnecessarily high pressure to
release the lock because of the lever arm of the release spring.  I moved
the spring about 4-5" closer to the pivot, and alleviated that issue.

Al...How much free tension do you have on the cable when the gear is down
and locked...? Maybe there is too much free play on the lock side and the
over center lock is not releasing before the gear starts up....

 

Steve;

 

The cable is just 'snug' when the gear is down.  Reducing the tension force
in the cable required to unlock the latch insures its release in a timely
manner - if it makes any difference in that regard. I had calculated the
cable tension required to release the latch, and it was in the hundreds of
pounds (don't remember the number).  More than that required to lift the
gear - seemed clearly excessive to me.  This hasn't shown up as a problem in
anyones plane that I know of; so it was just something I did to reduce the
stresses on the system in getting the gear travel started.
