Rodrig Goliescu (1882–1942) was a Romanian inventor, engineer, and Lieutenant, who built the avioplan, the first airplane with a tubular fuselage.The model, with a length of 1.2 m was successfully tested in 1909, having a take off angle of 30 degrees. The originality of this aircraft was the shape of the fuselage, designed for minimum drag and acting as a tube fan, similar to the way the modern vertical take off aircraft and helicopters are designed. This shape reduced drag and increased the efficiency of the propeller.

In Paris he sent a survey "Laws of air dynamics" to the French Academy, study that was published in "La France automobile et aéri
