The Teledyne CAE LJ95 (company designation: CAE 365) was a lift jet built by Teledyne Turbine Engines (then known as CAE and later Teledyne CAE) in the 1960s.[1]
Development
[edit]In 1961, Eli Benstein, Doug Oliver, and Marvin Bennett were assigned to go get some new business. To meet NATO requirements, Teledyne opted for the separate lift jet approach, and it conceived a high-thrust lift turbojet with a thrust/weight ratio of 20:1. An experimental lift jet engine (with a thrust/weight ratio of 12:1) built by CAE made use of lightweight materials and design techniques and operated horizontally.
After CAE's first lift jet tests, the USAF held a competition for a lightweight lift jet engine, and CAE, Pratt & Whitney, and General Electric competed for this contract. CAE was declared the winner, and in 1962 it was awarded a contract to develop and test a lift engine in the 4,000-lb-thrust class. The resulting LJ95 used very thin structural members to meet weight requirements. From 1962 to 1966 test runs of the LJ95 were carried out in a facility in the tower of one of CAE's buildings in Detroit, and the LJ95 accumulated 200 hours of operation without mishap.[1][2]
The LJ95 was explored by Northrop as one optional lift engine for the N-289 VTOL demonstrator project conceived in the 1960s.[3]
