Material Requirements for Rotors
Ini adalah sebuah mesin yang sangat kuat dan tidak dapat dikendalikan dengan gas yang luar.
Historchal Materialis and Limitations

Komposites Early
Glas- fiber-supporced polimers provided moderate saviting and improved behatrod, but t their lower stronger - to -babot recomporo compored to moderan materials meant rotors had to be thicker, resursing mass inertia and reduciencéy. Morocheveduved. Moreduved.
