Xperimental Autogyro/Gyrocopter

Image
 This is my second autogyro /gyrocopter , but first which I am designing completely on my own This tread is not real time, and the the design and build is going through iterations  MODEL-1 1. Direct control head 2. two blade rotor 3. teetering head 3 D print 4. Tractor  5. blade length -400mm Disk loading   AUW 650gms ..=23/5.4 =4.26 oz/sq ft  .. 4.26x2 =8.5  DID NOT fly It nosed up dramatically and stalled the blades did nor spin fast enough, the overall CG was not correct and was quite heavy MODEL -2 1. Direct control head 2. 3 blades 3. pusher 4. additional rudder control 5 reduced wt The fuselage is made of 10mm Al sq tube riveted together. The rotor hub was made of hardwood, with a Xray film acting as the hinge for roll control. The rotating plate was made of ply with again a Xray fil acting as the flapping hinge. It is a delta layout. The main rotating assembly comes from a 2206 outrunner motor.. the stator part Close up of the mast head Close up...

Prandtl Glider - Experimental

Image
 This is a small and simple Prandtl glider Span- 890mm, Root cord = 115mm, Tip Cord = 30mm, Sweep = 24 degree Will try out as a chuck, DLG and tow line It is a fairly simple contraction. The camber drops to 0 degree at 70% of span, and at the tip the camber is 0 and the washout is 9 degrees The topside.  The underside The fuselage is a just a stick to enable a small weight to be put way forward to get the CG right A side view. Notice the washout in the closer tip, the camber at the root  

Xperimental Variable camber aircraft

Image
Attaching a few pics of a fomie with variable camber wings. The camber is coupled with flaps... Basically leading edge flaps coupled with normal flaps... the model configuration in the radio on the "flaps" channel was critical. It also had normal ailerons , elevator and rudder. Each pair of the LE and the main flaps are operated by one servo. Activating the LE flap and the main flaps did allow the aircraft to fly at a higher AoA and slowly .. Would have to improve on the design to make the whole thing more rigid and try it on a larger aircraft
