Maurice Percheron Aircraft Prototypes and Projects

Hi,

the French Maurice Percheron designer joined the Donnet company in 1919,after replacement
Denhaut,and began to create a new series of aircraft,the "DP",consider a mystery in the world
of aviation,very little known info about him;

The DP-10 was triplane flying boat,may be a project,DP-15 was three seat seaplane,DP-18 was
three seat recce seaplane,does anyone know more ?.

Also in 1923,he created a unmanned drone aircraft project,may be the earlier in France,but
they were not interested.
