The invention is a propulsion system for a V/STOL type aircraft. In detail, the invention comprises a turbofan engine including a fan section, compressor section, combustion section, turbine section and nozzle section. The turbine section comprises a low-pressure turbine portion coupled to and driving the fan section and a high-pressure turbine portion coupled to and driving the compressor. The invention relates to the field of propulsion systems and, in particular, to a propulsion system for vertical and short takeoff and landing (V/STOL) aircraft. DESCRIPTION OF RELATED ART. The efficiency of a propulsion system for an aircraft is maximized when the velocity of the exhaust gases equals the forward velocity of the aircraft.

Importance of Rocket Propulsion • Propulsion system constitutes a large fraction of any launch system in terms of – Mass – Cost – Failures • Propulsion system is an important part of the vehicle (or satellite) for other applications • Rocket propulsion is key – to cost effective reliable access to space. Preliminary design of propulsion system for V/STOL research and technology aircraft The V/STOL Research and Technology Aircraft (RTA)propulsion system design effort is limited to components of the lift/cruise engines, turboshaft engine modifications, lift fan assembly, and propulsion system performance generation. The uninstalled total net thrust with all engines and fans operating at.

And rotor-type V/STOL aircraft and the session on propulsion covers V/STOL fan and jet propulsion systems. This session is therefore restricted to propeller, fan, and jet V/STOL aircraft types and does not deal in detail with the propul- sion system itself.

V/STOL short-haul transportation system discussed by Professor Miller in his. A propulsion model of the YAV-8B's engine and reaction control system is used to isolate aerodynamic forces and moments for model identification. Representative V/STOL flight data are presented.

The processing of a typical short takeoff and slow landing maneuver is illustrated. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA Cited by: 5. The integration of the propulsion system into the design of a vertical/short takeoff and landing (V/STOL) commercial transport for is presented.

On a V/STOL airplane it provides the force for lift and cruise, is the sole source of energy for control, and is powerful enough to handle emergencies including those within the propulsion system Cited by: 3.

A number of different powerplant systems have been and are being considered for supersonic V/STOL aircraft. Some of the main features of these different powerplants are described. As a result of studying the results of operation of successful and unsuccessful V/STOL aircraft in the powered lift condition, a number of real requirements for Author: W.

Lewis. In jet engine: Vertical and short takeoff and landing (V/STOL) propulsion systems. Propulsion systems that provide aircraft with the capability of both vertical and conventional forward flight represent a formidable challenge to the engine designer.

V/STOL aircraft have several major categories of engine arrangement. They are as follows. Figure 6: Overview of a notional V/Stol Propulsion Systems. book fan V/STOL aircraft for maritime patrol missions based on the XV-5A lift fan concept[12].

The papers presented cover a wide variety of aerodynamic and hydrodynamic applications including naval vehicles(A01); fixed-wing aviation(A01); V/STOL platforms(A01); propulsion systems and ground with interests in applied aerodynamics(A01); fluid mechanics and aircraft design will find this book of particular value(A01); as.

The mating of these new propulsion systems with different material, structural, aerodynamic and avionic technologies gave, in turn, origin to over projects of a novel “electric vertical aviation” symbolized by the acronym eVTOL (electric Vertical Take-Off and Landing).

The second factor is the rate at which mass is ejected from the rocket. A propulsion system for vertical take off and landing aircraft includes a forward compressor fan (40) and an aft compressor fan (42) downstream of the forward fan and in series flow communication with the forward fan.

The forward and aft fans are positioned in a central duct (26). A gas turbine engine (44) is in series flow with the forward and aft fans for driving the fans.

S.1 Spacecraft Propulsion Systems Spacecraft propulsion is based on jet propulsion as used by rocket motors. The principle of rocket propulsion was known as far back as B.C. In the 13th century solid rocket-powered arrows were used by the Chinese military. The Second World War and the cold war advanced rocket missile development in modern time.

This paper deals with control of V/STOL aircraft in powered-lift flight. A review of representative operational mission tasks is presented for the take-off, transition, hover and landing flight phases.

Characteristics inherent in the basic airframe and propulsion system and the behaviour associated with control augmentation systems are considered. The purpose of this document is to present a comprehensive, in-depth review of the serious efforts made in the development of VTOL and V/STOL concepts and aircraft other than the helicopter.

The time period covered is from the beginning of organized government-sponsored activity in the late 's through the present, during which a very large study and development activity has taken place. lift fan propulsion systems v/stol aircraft control This paper discusses aircraft control power requirements provided by lift fan systems.

Propulsion and Energetics Panel.]. Preliminary designs were developed for four generically different V/STOL airplane concepts. Two of the airplanes used lift/cruise fans and were designed to satisfy high altitude, subsonic Anti-Submarine Warfare (ASW) mission requirements.

The other two airplanes used different jet lift and lift/cruise propulsion concepts and were designed for supersonic, Deck Launched Intercept (DLI) mission.The Ryan XV-5 Vertifan was a jet-powered V/STOL experimental aircraft in the s.

The United States Army (US Army) commissioned the Ryan VZRY (re-designated XV-5A in ) inalong with the Lockheed VZ Hummingbird (re-designated XV-4 in ). It successfully proved the concept of ducted lift fans, but the project was cancelled after multiple fatal crashes unrelated to the lift.A hybrid-electric propulsion system combines the advantages of fuel-based systems and battery powered systems and offers new design freedom.
