Elias AJE Air Express

AJE Air Express
Role Mail plane
National origin United States
Manufacturer Elias
First flight c.1927
Number built 1
Developed from Elias M-1 Mailplane

The Elias AJE Air Express was a prototype mailplane built in the United States around 1927 by G. Elias and Brother.[1][2] The design was intended to be adaptable to a number of other roles,[1][2] but failed to attract any orders and did not progress beyond its single prototype.[1]

Design

The AJE Air Express was a development of the company's Elias M-1 Mailplane,[3] with which it was marketed side-by-side in 1926.[4] It was a single-bay, equal-span, unstaggered biplane of conventional configuration.[5] Its fuselage incorporated a 65-cubic-foot (1.8 m3) duralumin-lined mail compartment[2][3] and an open cockpit for the pilot.[2][5] The tail was of conventional design, and it was equipped with fixed, tailskid undercarriage.[2][5] Power was supplied by a piston engine in the nose driving a tractor propeller.[2][5] The ends of the wings were braced with N-struts, and in place of bracing wire, interplane bracing was achieved with steel tube.[2]

The fuselage and tail were built from welded steel tube, and the wings from wood.[2] The whole aircraft was covered in fabric.[2]

From the outset, Elias hoped that the mail compartment could also be fitted with cameras for aerial survey work, or be used as a chemical hopper for crop-dusting.[1][2] Despite this forward thinking, the aircraft failed to find a market.[1]
