pixelpilot Posted September 17, 2011 Posted September 17, 2011 Hi all, I'm currently part way through building some flight pedals using some drawer runners and welded steel frame work, Aproaching the phase where i have to design the pedals themselves. As far as i know your whole foot sits on the pedal but i may be wrong, The Saitek combat pedals look as though your heel is on the ground and the pedals are toe operated (does sound good for precice movement in rotary aircraft). Does it vary between aircraft? or which way is correct?
Ragtop Posted September 17, 2011 Posted September 17, 2011 Different pedals in different planes. The A-10C uses toe style pedals, fairly similar to the Saitek Combat pedals. Most military aircraft use this layout. Look at pictures of the Simped F-16 pedals, they are a pretty accurate depiction of most US fast movers. 476th vFG Alumni
pixelpilot Posted September 17, 2011 Author Posted September 17, 2011 cheers Radtop i'll take a look.
doright Posted September 18, 2011 Posted September 18, 2011 Many aircraft your heels are on the floor panel inflight, using the ball of your foot on the lower part of the rudder pedal. Only after touchdown do you raise your foot on the pedal to actuate the brake (ensures you don't touchdown with brakes on).
KLaFaille Posted September 18, 2011 Posted September 18, 2011 Just as more of a technical FYI, the A10 does not use a pedal setup like the F16 at all, in that the pedals are not connected and swiveling around a central axis. The pedals in the A10 are connected to hangers and rockers outboard of each respective pedal. Various pushrods and bell cranks are used to connect the pedals together and translate and invert the motion of whichever pedal is pushed onto the other. There is a crossover crank attached to a port side bell crank which actuates a pushrod going to an idler, which then goes back further to interface with more yaw system components.
Ragtop Posted September 18, 2011 Posted September 18, 2011 Mechanically, of course they are totally different, when I said they were similar I was referring only to the actual footplate design and the way the pilot operates them. Pixelpilots' pedals are going to be (unfortunately) confined to life under a screen, so the way they interface with the plane wasn't implied when I mentioned that they were similar. Nonetheless a very interesting bit of information! 476th vFG Alumni
KLaFaille Posted September 18, 2011 Posted September 18, 2011 Hi Ragtop, I know what you meant and I wasn't trying to correct you in any way, just throwing the info out there. :) Red
Deadman Posted September 18, 2011 Posted September 18, 2011 Here is a picture and a drawing form my collection that will give you a clear view of the system. https://forum.dcs.world/topic/133818-deadmans-cockpit-base-plans/#comment-133824 CNCs and Laser engravers are great but they can't do squat with out a precise set of plans.
doright Posted September 19, 2011 Posted September 19, 2011 Looking at the diagram another though struck me. In some flight test data I looked at (not A10) the pilot could apply close to 300lbs of force to the top of the brake pedal. I can't remember the figure used for the base of the rudder pedal but it was even higher. Multiply by some safety factors and fitting factors and thats why the system looks much sturdier then you would think.
