Bréguet 902 Cinzano. The Bréguet Br 902 Cinzano was a French training glider produced in the 1950s by Société anonyme des Ateliers d'aviation Louis Bréguet

Design and development
In response to a need for replacing the Caudron C.800 training glider with a contemporary high performance trainer, Bréguet designed and built the Br 902 Cinzano prototype, with parts in common with the Br 901 and Br 904. Production aircraft would have been optimised for production and also used new manufacturing techniques, particularly for the wings, which were intended to be built using the hollow shell method; high-accuracy plywood skins laid up in jig moulds with structure added in the mould to retain the high accuracy surfaces.

Construction was of welded steel tube for the fuselage with wood for wings and empennage. The fuselage was covered in fabric, with plywood for areas requiring more resilience. Flying controls, wings and empennage were built up from wood with plywood high strength members, covered with fabric. The instructor and pupil sat in closed tandem cockpits covered with Plexiglass canopies. Control was via conventional ailerons, elevators, operated by rods and rudder operated by cables, with airbrakes on the wings for approach control. The undercarriage consisted of a single mainwheel fitted with a hydraulic brake, rubber sprung tail-skid, with protection skids on the wing-tips.

The first prototype, Br 902-01, flew for the first time on 14 May 1957 piloted by  Paul Lepanse, but despite good performance and flying characteristics, the Br 902 failed to sell well; only a small production run of 6 gliders was built.

Couzinet 33. The Couzinet 33 Biarritz was a French long-range monoplane built by René Couzinet in the early 1930s.

Design
The Couzinet 33 was made of wood, with a thick cantilever wing with thickness of  at the wing roots; with no dihedral on the upper surface. The wing main-spar was  continuous from wing-tip to wing-tip; and the rear spars attached to the fuselage sides. The aircraft was covered with birch plywood, with the fuselage thinning to the rear, forming the characteristic tail of a René Couzinet signature aircraft.

Couzinet designed the plane when he was 27 years old with only 28 flight hours.

Operational history
The biarritz made its first flight in November 1931, clocking up 27 hours flying before departing on a flight from Paris to Nouméa. From 6 March 1932 to 5 April 1932 Emile Munch, Max Dévé and Charles Verneilh flew the Biarritz from France to New Caledonia, the first time a direct flight had succeeded. On arrival at Nouméa the aircraft crashed and was destroyed.

Biarritz No.2
After the wreckage of the Biarritz was shipped back to France, a second aircraft was built using salvageable parts of the first. This aircraft set off on a non-stop flight from Paris to Algiers on 30 October 1933, flown by Charles Verneilh, but crashed in fog at Blaisy-Bas in the Côte-d'Or.

Sling Aircraft Sling TSi. The Sling TSi is a South African four-seat, single-engine, low-wing homebuilt aircraft sold in kit form by Sling Aircraft of Johannesburg South. It was developed from the Sling 4.

The Sling TSi first flew in 2018, with kits being shipped to builders in fall 2018.

Design and development
The aircraft was developed in 2018. The Sling TSi is an all-metal, low-wing, fixed tricycle gear homebuilt aircraft. The airplane is equipped with the new Rotax 915iS engine and was the inspiration for the designation of TSi. Parts of the wings and fuselage were reinforced and outfitted with flush riveting for increased strength and reduced drag over the Sling 4.

The UK Light Aircraft Association has limited the airframe safe life to 1600 hours due to a stress point in the wing design.  Additionally, the LAA has deemed the flight characteristics unsuitable for flight in IMC.

Operational history
The first Sling TSi in the USA was shown at EAA AirVenture Oshkosh in 2018.

In a review for KitPlanes, writer Paul Dye said, "...it lives up to its design goals. We flew with four full sized adults from a field with a density altitude of 9,000' and had to throttle back to keep from exceeding redline when we leveled off at 10,000. Later, operating off of a dry lakebed in the high desert, with temperatures of 100 degrees, we never had to worry about engine cooling - and it handled like a fine touring machine."

A company demonstrator Sling TSi flew non-stop from Torrance, California, to Tampa Executive Airport on its way to Lakeland, Florida for Sun 'n Fun 2019 in 13.5 hours. The aircraft carried an additional  of fuel over the normal  long-range tanks and benefited from tailwinds en route.

In July 2019 the company did a ceiling expansion test and flew non-stop from Torrance, California to Wittman Regional Airport  to attend EAA AirVenture Oshkosh for 9.75 hours. The aircraft reached a final height of 27,000 feet.

Variants
During EAA AirVenture Oshkosh in 2019 the development of a new high-wing variant, the Sling HW was announced.

Shading coil. A shading coil or shading ring (Also called Frager spire or Frager coil) is one or more turns of electrical conductor (usually copper or aluminum) located in the face of the magnet assembly or armature of an alternating current solenoid. The alternating current in the energized primary coil induces an alternating current in the shading coil. This induced current creates an auxiliary magnetic flux which is 90 degrees out of phase from the magnetic flux created by the primary coil. 

Because of the 90 degree phase difference between the current in the shading coil and the current in the primary coil, the shading coil maintains a magnetic flux and hence a force between the armature and the assembly while the current in the primary coil crosses zero. Without this shading ring, the armature would tend to open each time the main flux goes through zero and create noise, heat and mechanical damages on the magnet faces, so it reduces bouncing or chatter of relay or power contacts.

Shaded-pole AC motors

A shaded-pole motor is an AC single phase induction motor. Its includes an auxiliary winding composed of a copper ring called a shading ring (or shading coil with more than one turn).

The auxiliary winding produces a secondary magnetic flux which, along with the flux from the primary coil, forms a rotating magnetic field suitable for applying torque to and rotating the rotor. These devices are typically used as low-cost motors for microwave oven fans.
