Nout’s structure

New_slider_1

Towing gliders is above all an Aerial Work !

A tow plane must first respond to two essential criteria:

  • expected performance climb and take off (for a small cost)
  • strength linked to the implementation of several cycles (takeoff, climb, dive, landing).

So why use tourist aircrafts and/or fragile microlight aircrafts to make this work ?

We imagine easily heresy due to technical choice of carbon fiber aircraft on pebbles fields as we sometimes see in the world of gliding.
Visible on some airfields, the leading edges of the tail planes stoned, aluminum forged Rallyes’ propellers hammered by pebbles, are proof.
Which ones are the results of such shocks on a carbon fiber structure (tail surfaces, or propeller) covered with a thin layer of gel-coat?
What about reparability in a club after intensive use and small handling errors (Choc of a wing against a hangar wall) or worse in a pothole on the slopes of grass runway or hard landing…
because it finally arrived one day.
Fiber dents, small delaminations, bursts into the gel-coat or other pleasures that a gliding club will not repair onsite, and must deal with the manufacturer or an authorized workshop. it costs a lot of downtime and certainly too much money.

It is the same with an aluminum structure (eg Rallye) whose the technical mastery, like fiber / resin are the domain of professionalism (both in the gesture and in the tools). So …

No !!!

Gliding does not need this . The budget of the clubs is already sufficiently tainted by the poor performance of existing tow planes.

A tow plane must be Simple , Sober , Strong , Efficient , especially repairable in situ , and to do that, it must be made in conventional materials (wood, fabric, steel and some fiberglass / epoxy for complex non structural parts).
Well done it will be light, strong, and most maintainable cheaply and in a short time .

The dedicated tow plane project “Nout” integrates these constraints:

welded tube truss fuselage structure

In a classical structure (wooden wings and fabric, welded tube truss fuselage structure), it is thought to be easily made in gliding club.

Available in Kit , the most complex organs will be supplied:

  • welded tube truss fuselage structure
  • wing leading edge + wing spars
  • legs, Hood
  • nondevelopable canopy elements

Remains the responsibility of the club to finish the assembly, to make the integration of the power plant and finishing the structure.

“Nout” consists of 5 major parts:

  • Fuselage + legs

Fuselage

  • Power plant

GMP

  • vertical tail

empennage_vertical

  • horizontal tail (here a half horizontal tail)

empennage_horizontal

  • Wing (here a half wing)

Covered by gliding club , the team responsible for building of the kit then integrates all the technical knowledge and the culture associated with the aircraft. It can then no problem taking into account the maintenance and even major repairs in a relatively short time at an affordable cost (the workforce of volunteers being free).
