Condor - Thermal - powered glider

-

 A thermal plank with low wing loading and a low drag airfoil.

It has elevons and an active rudder.



Dimensions and details

Wing Span panel 1 =695 mm, Wing Span panel  2 =298 mm, Total = 1986mm

The Airfoil - HS 117.

Cord panel 1 =250mm, Cord panel 2 (tip) =150mm

Sweep panel 1 =0, Sweep panel 2 (tip) =30mm

Dihedral panel 1 = 20mm, Dihedral panel 2 = 150mm

The Airfoil is HS 117.

Vertical Tail to wing TE distance = 410mm, Vertical Tail cord 100mm, Vertical tail span 230mm

Control surfaces are elevons and rudder

The wing is hotwired out of EPS and covered with fiber-glass (vacuum bagged). The central portion has a CF tow (5mm) running on top and bottom. The two outer panels of 298mm each are detachable for ease of carrying. 

The elevon cord is 40 mm and it is across the whole length of the inner panel. It has a kevlar hinge built into a skin, and the underside gap sealed with mylar (BO_PET) strip




Wing area in inches = 723.4 sq inch

Electronics

2212 980kv motor, 30A esc,  9x5 folding prop, 2200mah 3s bty, 2 x 17 gm servos, 1X 9 gm servo,

AUW = 903gm, 31.85 oz (with a 2200mah 3S bty)

Wing loading = 6.34 oz/sq ft

Wing cubic loading = 2.8

Spiral stability = 4.63, Vv = 0.015, Eda = 10.47

CG @20% SM = 1.54cm, @15% SM = 2.73cm

    Après avoir obtenu mon planeur thermique, je l'ai sorti pour un vol d'essai et j'ai pu aller plus haut et rester plus longtemps dans les airs. J'avais l'impression de pouvoir voler pendant des heures avec. Je suis un grand fan de ce modèle.

Flipper - Plank flying wing SAL

Image
 This is a Plank flying wing for SAL or bungee The dimensions are  Span = 875mm, Root cord = 260mm, Tip cord = 160mm, sweep = 60mm. 20mm constant cord full length elevons The wing is hotwired out of EPP and then laminated with thin iron-on laminating film. The airfoil is PW51 7% thick at the root and PW51 7.5% thick at the tip. It has a 1.5 degree washout and a 45mm dihedral at the tips.  It has one 2mmCF spar glued to the bottom positioned at 40% cord. There is also a spar on the top surface biased to the rear to avoid elevon reversal. Two 9g servos are positioned vertically into slots cut on the top of the wing. The position of the servos are driven by the thickness of the wing at that part and distance from CG. The full length elevon is a tapered 3mm balsa with fiberglass lamination. ....Note I had to increase the elevon cord at the tips by 12mmto improve the control response (after the first flight trials) The fuselage is a 3mm CF rod glued onto the bottom of the wing...

Angor-Rot & Hot-Rod hotliner RC plane

 Fast, hotliner design These two are built for speed, and unlike a 3 surface (wing , tailplane and rudder) design, they are wings (delta). The thought was having the max wing area for a given wt and strength and with the least friction/profile drag, and of course ease of construction. (ignoring  difference in Induced drag). Construction is composite, foam, glass fibre, carbon fibre and vacuum bagged,  resulting  in a very strong lightweight structure for its wt. Airfoil is PW 51, with a 1.5 degree washout at the tips. Small wing tips are added to draw out the tip vortex. The LE is reinforced with CF. The wings tips and the centre section of the underbelly has some CF  reinforcements built in. It has 2 layers CF tow of different lengths acting as spar. The paint pattern has been painted directly onto the skin and then vacuum bagged. The control surface hinges are live hinges built into the glass fibre skin. The servos and push-rods are embedded with the wing. All...

DESIGN This design explores the region between a plank and a swept wing flying wing, and to try and get the best of both worlds to whatever extent possible.... The major balancing acts were being efficient across a large speed range, good C l /C d , less twist, and maintaining good flight characteristics. PLAN & DIMENSIONS A span of 1200mm was chosen to keep it a one-piece plane.  - Sweep is a very moderate 13 degrees measured at LE, and even lesser when measured at 1/4 AC line. - - Aspect ratio =- 6.3... (adequate wing loading with the set span of 1200mm span) - Taper ratio= 0.65 and Twist - (-)1 degree..... (close to elliptical lift distribution, less induced drag, while maintaining decent Re and flow characteristics at the tips, good stall characteristics) - Airfoil is PW51.. (good cl/cd, adequate +ve cm, and minimum trim losses).  - A central tailfin is chosen over wing tip fins.... (due the the less moment arm and the issues arising out of a badly designed wing tip ta...
