Zusammenfassung:	A variable vane assembly is disclosed which entails a vane arm which integrally engages with a vane stem without the use of threaded fasteners. The vane stem has a tip with parallel slots on opposite sides which are spaced below the end of the tip. At the end of the tip is an end slot which is perpendicular to the parallel slots. The tip of the vane stem has a ramped side parallel with the end slot. The vane arm is a flat wide metal strip that serves as the vane blade and integrally connects with the vane stem using two ears, which are turned inwards to engage with the parallel slots in the wave stem. Additionally, a central leaf exists between the two ears which turns downwards to fit in the end slot in the tip of the vane stem. The central leaf thereby acts as an axial retainer and allows the vane arm to be rotated with the rotation of the vane stem.
