• The VTOL (vertical take-off and landing) aircraft may be powered either by a thrust vectoring propulsion engine or by a normal propulsion engine which incorporates a valve to divert high pressure combustion gas to vertically mounted tip turbine and fan combination units to provide lift in the VTOL mode. The third option is to use a direct lift engine, independent of the propulsion engine and dedicated to VTOL mode only. Since the requirements for normal propulsion and VTOL mode may not always be mutually compatible, the optimization of the design and operation of thrust vectoring as well as the normal propulsion plus fan in wing systems could be impractical. For inter city civil VTOL aircraft, the direct lift engine could be a better choice as it might be designed to meet the noise, pollution and fuel economy criteria. The paper examines systematically the basic design criteria for direct lift engines. Although the thrust vectoring propulsion engine has established a leading position for military aircraft, the direct lift engine may have a place for VTOL inter city civil airliners.
