This paper presents a hierarchical application of Discrete Event Supervisory (DES) control theory for intelligent decision and control of a twin-engine aircraft propulsion system. A dual layer hierarchical DES controller is designed to supervise and coordinate the operation of two engines of the propulsion system. The two engines are individually controlled to achieve enhanced performance and reliability, necessary for fulfilling the mission objectives. Each engine is operated under a...

The NASA/Langley Personal Air Vehicle (PAV) Exploration (PAVE) and the DARPA (Defense Advanced Research Projects Agency) Dual Air/Road Transportation System (DARTS) projects were established to investigate the feasibility of creating vehicles which could replace, or at the very least augment, personal ground and air transportation schemes. This overall goal implies integrating several technology areas with practical everyday transportation requirements to design a class of vehicles which will...

A set of computer programs has been developed to estimate the takeoff and initial climb-out maneuver of a given aircraft in three-dimensional space. The program is applicable to conventional, vectored lift and power-lift concept aircraft. The aircraft is treated as a point mass flying over a flat earth with no side slip, and the rotational dynamics have been neglected. The required input is described and a sample case presented.

Presented is an analytical investigation of the aerodynamic forces acting on wing-propeller combinations including the effects of propeller slipstreams. The results of the developed theory are then applied to typical two- and four-propeller VTOL and STOL wing configurations. Correlation with existing test data is shown to be satisfactory. Consideration is also given to such associated items as the effects of the slipstream on (1) wing stall (2) aircraft take-off and landing performance and (3)...

The study was undertaken to find an easy-to-use take-off distance prediction method and to evaluate its applicability to STOL aircraft. For the purposes of the study STOL aircraft were defined as those requiring a take-off ground roll of less than 1000 ft. Two existing take-off ground roll estimate methods were evaluated by comparing predicted values with available data for several STOL aircraft. The resulting accuracies were respectively within 9% and 11% error. It was found that one of these...

Configurations used consisted of: open propellers, ducted propellers, side by side jets, and ground effect machines of the plenum and annular nozzle type. Disk loadings of 2 to 150 pounds per square foot and Z/ D ratios of .25 to 3 were investigated. Data were obtained to determine: the over-all flow pattern, flow velocities,...

On the basis of trade-off analysis of Launch and Recovery Systems for ARPV, the conventional take-off and landing method using high lift wing (STOL) technique, own thrust and arresting gear system emerged as the undisputable leader among the candidate systems. The next system in succession is the STOL configuration using modified SATS catapult conventional gear and arrester gear.

A SIMPLE THEORETICAL EXPLANATION OF THE AERODYNAMIC COOLING OFTEN FOUND NEAR THE BASE AND IN THE WAKE OF BLUFF BODIES IS PRESENTED. THE THEORY IS BASED ON COMPRESSIBLE POTENTIAL FLOW AND MAKES USE OF THE ENERGY INCREMENT ASSOCIATED WITH THE UNSTEADY VELOCITY-POTENTIAL TERM OF THE ENERGY EQUATION IN CALCULATING THE TEMPERATURE AT A POINT IN UNSTEADY FLOW FOR THE GENERAL CASE. THE CASE OF TWO-DIMENSIONAL FLOW PAST A CYLINDER IS EXAMINED IN DETAIL.

This Research Technical Memorandum presents suggestions for a specification on flying and handling qualities requirements for subsonic V/STOL aircraft. In addition to including the ideas of many others, the authors have incorporated two basic suggestions: (1) the use of a pilot rating system (since the ultimate measures of handling qualities are determined by the pilot) and (2) the use of servo-analysis techniques and terms to define quantitative requirements. There are no statistical or...

Specific areas investigated include wing stall during transition, minimum wing size for stall-free transition, and the effects of slipstream on aircraft pitching moments. In addition, a stability analysis was performed, and analog computer techniques were used to determine the feasibility of utilizing the slipstream for stability augmentation. Finally, the effects of the nonuniformity of slipstream velocity and wing geometry modifications on performance were analyzed.

Modifications were made to the existing Large-Scale STOL fighter model to simulate a V/STOL configuration. Modifications include the substitutions of two dimensional lift/cruise exhaust nozzles in the nacelles, and the addition of a third J97 engine in the fuselage to suppy a remote exhaust nozzle simulating a Remote Augmented Lift System. A preliminary design of the inlet and exhaust ducting for the third engine was developed and a detailed design was completed of the hot exhaust ducting and...

The objective of this study was to determine the feasibility of refueling V/STOL aircraft, including helicopters, by means of a ship-based refueling device which would circumvent the need for landing. Twp alternative high fuel flow rate systems are projected through exploratory designs. Feasibility is indicated through analyses of solutions required to support and stabilize the refueling device for engagement by V/STOL aircraft within the limits of available aircraft control power in a sea...

The vertical take-off and landing (VTOL) and high-speed cruise capability of the NASA Large Civil Tilt-Rotor (LCTR) notional vehicle is envisaged to enable increased throughput in the national airspace. A key challenge of the LCTR is the requirement to vary the main rotor speeds from 100% at take-off to near 50% at cruise as required to minimize mission fuel burn. The variable-speed power-turbine (VSPT), driving a fixed gear-ratio transmission, provides one approach for effecting this wide...
