2.1   Airframe

 

 

Wing:  high  placed,  strut  braced,  constant  chord.  Wing  section  is  P-llla-15%. Wing  primary 
structure  consists   of  a  single  spar,  ribs  and  aft  web.  Forward  of  the  spar  the  wing  has

 

2024T3  aluminum  alloy  skin  of  0.5-0.8  mm  (0

.

020-0

.

032  in)  sheet,  which  together  with  the 

spar   web   forms   the   wing   torsion   box

.   

Aft   of   the   spar   the   wing   is   covered   with 

thermoshrinkable   fabric  on  top  and  bottom  sides.  Wing  ribs  are  made  of  6061T6  sheet  of

 

0

5-0.8  mm  (0.020-0.032  in)  thickness.  The  spar  is a  riveted  structure  consisting  of  a  web, 

made  of  0

.

8 mm  (0

.

032  in)  6061T6  sheet,  and  caps,  made  of an  extruded  section  (D16chT 

alloy  angle).  The  wing  strut  attachment  bracket  and  front  attachment  bracket  of  the  wing 
are  fixed  to  the  spar.  The  rear  attachment  bracket  of  the  wing  is  fixed  to  the  aft  web.  The 
flaperon  (drooping  aileron)  hinge  brackets  are  fixed  to  ribs  No

1,  5,  9  and  13.  All  brackets 

are made  of 5 mm  2024T3  sheet.

 

 

The  primary  structure  of  the  flaperon  consists  of  the  leading  edge  skin

spar,  trailing  edge 

section  and  ribs.  The  LE  skin  and  spar  comprise  the  torsion  box

.  

Flaperon  covering   is 

made  of synthetic  thermoshrinkable  fabric

.

 

 

The  fuselage  is  an  all-metal  structure

The  mid  section  is  made  of  the  2024T3  aluminum 

alloy  bent  sheet  sections  of  1

.

5  to  2  mm  (0.063  to  0.080  in)  thickness,   which  form  the 

edges  of  the  mid  section.  The  tail boom  is  a monocoque  structure  made  of  0

.

8  mm  (0

.

032 

in)  2024T3  aluminum  alloy  sheet.

 

 

Engine  cowling  is made  of composites.

 

 

The  fuselage  has  6  frames  (bulkheads)

Frames  No.  1,  2,  4,  5  and  6  are  press-formed  of 

an  aluminum   alloy  sheet;  frame  No.  3  is  made  of  bent  sheet  sections

.  

Power  plant  and 

nose  LG  attachment  points  are  attached  to  the  frame  No.  1,  the  engine  mount  taking  part 
in transferring  the  loads  from the nose LG onto the fuselage  structure.

 

 

The  wing  and  strut  attachment  brackets  as  well  as  the  main  LG  legs  attachment  brackets 
are  attached  to the frame  No.  3. Frames  No.4, 5, 6 are installed  in the tail boom.

 

 

The fin and  ventral  fin with the tail wheel  are attached to the frames  No.  5 and 6

.

 

 

The  bottom  and  part  of  the  topside  of the  mid  fuselage  section  are  covered  with  aluminum 
alloy  sheets  of 0

.

5 mm  (0.020  in) thickness.

 

 

The doors,  cockpit  and part  of the fuselage  have  windows  of organic  glass.

 

 

The  primary  structure  of  the  stabilizer  consists  of  ribs  and  a  spar.  The  skin  is  a  2024T3 
aluminum  alloy  sheet  of  0.5  mm  (0.020  in)  thickness

The  stabilizer  has  brackets  of  its 

attachment  to fuselage  and  3 elevator  hinge  brackets.

 

 

The fin, structurally  similar  to the stabilizer,  is made  as integral part  of the fuselage. 

Elevator  and  rudder  structures  are similar  to that of the flaperons.
