Patent AT-1913-64439

From Inventing aviation
Jump to navigation Jump to search

This was filed a mere four days before Patent HU-1913-62204 and this Austrian patent may be the earliest-filed offspring patent of that which we have designated as Patent DE-1912-266327, the latter still seemingly missing from Espacenet. This is an overall airplane design which related well to his slight focus on propellers. This latter emphasis seems to have been the key point at which his father the designer and industrialist Albert Hirth seems also to enter our fields of interest.
