Kinetographic Determination of Airplane Flight Characteristics (open access)

Kinetographic Determination of Airplane Flight Characteristics

The author's first experiments with a glider on flight characteristics demonstrated that an accurate flight-path measurement would enable determination of the polar diagram from a gliding flight. Since then he has endeavored to obtain accurate flight measurements by means of kinetograph (motion-picture camera). Different methods of accomplishing this are presented.

Duralumin and Its Corrosion (open access)

Duralumin and Its Corrosion

The types of corrosion and factors of corrosion of duralumin are investigated. Salt water is the most common of the corroding media with which designers have to contend in using duralumin in aircraft and ships.
