This book was released on 1978 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies have been conducted on an Air Cushion Landing System for the Australian Jindivik target drone aircraft. Analyses are presented of the airflow and yaw thruster control systems, and the vehicle stability with a deployed recovery trunk is assessed. The vehicle touchdown and slideout on a recovery trunk are presented, and the design of an improved retention/release system is shown. (Author).

This book was released on 1973 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems associated with existing recovery systems include difficulty in mid-air retrieval of RPV's in excess of 1500 lbs; high operations and support costs of parachutes, recovery helicopters, other aircraft and their crews; long recycle time; paving quality requirements for wheeled or skid type landing gear; and frequent damage of RPV's recovered by parachute/attenuation bag or parachute/mid-air recovery systems. Accordingly, this preliminary design study report describes an air cushion landing system (ACLS) applied to the 3,000 lb Jindivik Mk 3A unmanned aircraft. The ACLS is stowed for cruise flight in a clean aerodynamic fairing on the underfuselage, resulting in a minimum performance degradation. For recovery, hinged clam-shell type doors are unlatched, and open, permitting inflation/deployment of an inelastic type elongated toroid-shaped trunk. The trunk is inflated and blown with bleed air tapped off an existing port on the Jindivik's Viper Mk 201 engine. After landing, the aircraft is placed on a fixture and the trunk is manually restowed in the fairing. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: The report presents results of a concept feasibility and formulation study of Air Cushion Landing Systems for recovery of unmanned aircraft (Remotely Piloted Vehicles). A modified Ryan Model 147G drone or special purpose aircraft was investigated for possible use in a low cost flight test demonstration of air cushion landing gear concepts on an existing unmanned aircraft. Recovery by horizontal landing on an air cushion landing system is compared with recovery with a mid-air recovery system. (Author).

Download or read book Air Cushion Landing System Performance on a Tenth Scale Model Jindivik RPV written by Philip M Parker (Jr) and published by . This book was released on 1973 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on an air cushion landing system ACLS installed on a tenth-scale model Jindivik RPV. The model has the correct Froude-scaled values of weight, center of gravity cg and moment of inertia about all three axes. The results of these tests were compared to the results of similar tests conducted on the ACLS of a full-scale model Jindivik. Static tests on the tenth- scale ACLS determined the heave stiffness to be 11 lb per in., the pitch stiffness to be .155 lb ft per deg (for a nose down moment) and the roll stiffness to be .0048 lb ft per deg. These values were within 60% of the full- scale values. Drop tests showed the maximum load at the cg of the model to vary between 2.2 g's at the scaled nominal landing rate of descent, to 5.4 g's at the maximum landing rate of descent.

Download or read book Air Cushion Landing System Drop Dynamics Theory Mechanical written by Frederick C. Bauer and published by . This book was released on 1973 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mechanical analog Vertical Energy Absorption Model (VEAM) is developed to predict the dynamics of an Air Cushion Landing System (ACLS) in the vertical dimension. Three degrees of freedom and thus three primary modes of oscillation are investigated: heave, pitch and roll. Data from Air Force Flight Dynamics Laboratory Tests of a full-scale Australian Jindivik drone are used to develop and verify the model. The VEAM study demonstrates that the use of a mechanical analog prediction scheme for an Air-Cushion Landing System has sufficient merit to warrant further investigation. It shows that a mechanical analog model can predict system response within the model domain of three degrees of freedom without knowledge of the numerous and varying trunk and cushion parameters if the mode spring and damper coefficients are provided.
