The aeroshape features a high-sweep near double delta-shaped configuration, equipped with two functionally independent body flaps, which can be used for both longitudinal control (i.e., elevon mode) and lateral-directional control (i.e., aileron mode). The spacecraft is intended as a multipurpose vehicle for future International Space Station payload and/or crew servicing and support, able to perform a lifting re-entry from Low Earth Orbit and to land on a conventional runway. This paper deals with the evaluation of low-speed longitudinal aerodynamic performances of a vehicle concept with an unconventional blended wing-body aeroshape. This paper gives a brief overview of the Phoenix mission and elaborates on the flight data analysis and of the preceding wind tunnel campaigns, to allow a comparison of results from different approaches. A specific emphasis was placed on the evaluation of the on-board navigation system, air data sensor, aerodynamic model, landing gear effects and ground roll characteristics. Methods of system identification were applied to the flight data to evaluate the performance and to improve the design models and databases for future applications. Three automatic landing tests were completed successfully in May 2004. The shape of the test vehicle was derived from the suborbital RLV concept Hopper. The Phoenix vehicle was designed to flight demonstrate the automatic and un-powered horizontal landing of a representative, winged reusable launcher vehicle (RLV). While GroupTools main focus is group activities, a few other features are available as well.Within the framework of the German ASTRA (Advanced Systems and Technologies for RLV Application) program, the Phoenix project was established to implement experimental steps towards the development of a next generation space transportation system. GroupTools is a lightweight viewer (Text only) that includes features to easier deal with SecondLife group activities such as sending notices and IM's. Second Life and Open Simulator messaging client for all Android powered devices. Supports desktop and all mobile browsers, allows switching between devices. Light-weight feature rich non-graphical client, ideal for situations where full 3D rendering client is less than ideal option, for instance, an office environment, running on low performance computers and similar. These viewers omit some aspects of the full viewer functionality. Genesis is a blazingly fast, high performance 1.23 style viewer for Second Life, offering the very latest features, never seen before in a Legacy viewer. Singularity strives to combine the beloved look and feel of Viewer 1.23 with the latest and greatest of available technology, and to stay compatible with future Second Life changes and features. The RLV enhances your experience when you use it in conjunction with RLV-compatible objects, which are able to restrict the user from detaching items, receiving IMs, hearing chat, teleporting etc. It's about taking a fresh look at things and attempting to do them better. Our focus is stability, usability, privacy and plenty of new original home grown features. Kokua aims to be the viewer of choice for RLV users who want Marine Kelley's original implementation with more bells and whistles than Marine's own viewer.Ĭatznip aims to refine and reinvent your window into Second Life. Kokua provides releases for PC, Mac and Linux with and without Marine Kelley's RLV together with a broad selection of original features and the best from other viewers. The next generation viewer from The Phoenix Firestorm Project, Firestorm is based on the LL V3 LGPL code and offers extensive interface customizability including V1 skin options, feature and option rich with 24/7 support.Ī hybrid viewer based on a mixture of official sources and custom code aimed specifically at experienced users, with emphasis on the visuals. The primary goal of Black Dragon is to enhance and refine the visuals of Second Life as well as having unique design approaches and features. Uses non-standard and misleading values for avatar complexity These viewers are projects that are updated regularly to track new developments in the Linden Lab viewer, and implement a full graphical environment.Īn experimental Second Life™ viewer striving to be at the forefront of stability, performance, and technological advancement in the open-source metaverse viewer field. Beware of third-party viewers that are not in the Viewer Directory: they have either declined to self-certify their compliance with Linden Lab policies or been refused for noncompliance with the policies. Linden Lab provides a Policy on Third-Party Viewers to promote a positive and predictable experience for all Second Life Residents. You may connect to Second Life using software released by a third-party developer. 4 For developers: how to apply to list a viewer in this directory.
