Application to the Flight
Journal name 000(00):1–13 A Methodology for Vehicle and Mission ©The Author(s) 2010 Reprints and permission: Level Comparison of More Electric sagepub.co.uk/journalsPermissions.nav DOI:doi number Aircraft Subsystem Solutions - Application http://mms.sagepub.com to the Flight Control Actuation System Imon Chakraborty∗ and Dimitri N. Mavris† Aerospace Systems Design Laboratory, Georgia Institute of Technology, Atlanta, GA 30332, USA Mathias Emeneth‡ and Alexander Schneegans§ PACE America Inc., Seattle, WA 98115, USA Abstract As part of the More Electric Initiative, there is a significant interest in designing energy-optimized More Electric Aircraft, where electric power meets all non-propulsive power requirements. To achieve this goal, the aircraft subsystems must be analyzed much earlier than in the traditional design process. This means that the designer must be able to compare competing subsystem solutions with only limited knowledge regarding aircraft geometry and other design characteristics. The methodology presented in this work allows such tradeoffs to be performed, and is driven by subsystem requirements definition, component modeling and simulation, identification of critical or constraining flight conditions, and evaluation of competing architectures at the vehicle and mission level. The methodology is applied to the flight control actuation system, where electric control surface actuators are likely to replace conventional centralized hydraulics in future More Electric Aircraft. While the potential benefits of electric actuation are generally accepted, there is considerable debate regarding the most suitable electric actuator - electrohydrostatic or electromechanical. These two actuator types form the basis of the competing solutions analyzed in this work, which focuses on a small narrowbody aircraft such as the Boeing 737-800. -

Differential Throttling and Fluidic Thrust Vectoring in a Linear Aerospike
International Journal of Turbomachinery Propulsion and Power Article Differential Throttling and Fluidic Thrust Vectoring in a Linear Aerospike Michele Ferlauto , Andrea Ferrero * , Matteo Marsicovetere and Roberto Marsilio Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Torino, Italy; [email protected] (M.F.); [email protected] (M.M.); [email protected] (R.M.) * Correspondence: [email protected] Abstract: Aerospike nozzles represent an interesting solution for Single-Stage-To-Orbit or clustered launchers owing to their self-adapting capability, which can lead to better performance compared to classical nozzles. Furthermore, they can provide thrust vectoring in several ways. a simple solution consists of applying differential throttling when multiple combustion chambers are used. An alternative solution is represented by fluidic thrust vectoring, which requires the injection of a secondary flow from a slot. In this work, the flow field in a linear aerospike nozzle was investigated numerically and both differential throttling and fluidic thrust vectoring were studied. The flow field was predicted by solving the Reynolds-averaged Navier–Stokes equations. The thrust vectoring performance was evaluated in terms of side force generation and axial force reduction. The effectiveness of fluidic thrust vectoring was investigated by changing the mass flow rate of secondary flow and injection location. The results show that the response of the system can be non-monotone with respect to the mass flow rate of the secondary injection. In contrast, differential throttling provides a linear behaviour but it can only be applied to configurations with multiple Citation: Ferlauto, M.; Ferrero, A.; combustion chambers. -
Setting up Ailerons and Flaperons on a DLG (Discus Launch Glider) by Andy Kunz
Setting up Ailerons and Flaperons on a DLG (Discus Launch Glider) by Andy Kunz Originally Posted by kgantz: While waiting for parts to be delivered I am still reading a lot about how to initially set up ailerons / flaperons. One of the best descriptions I've found is this post in the DLG forum. After reading this post, I understand that flaperon trim and aileron trim are handled separately by the radio. This is not obvious to people who have not done this before but, I guess because you are working with 1 moving surface but it has 2 jobs, trimming has to work a little differently for each job! So now my question is, on the Spektrum radios-- DX 9 in my case, is the aileron portion of the adjustment done with Dual Rates as suggested by the poster or is there a different way. Reply by AndyKunz: The logic is that one is a roll trim, the other is a camber trim. You'll find that we're pretty consistent with that sort of thing throughout the radio. Use the Dual Rates to adjust travel based on a switch, for instance in launch mode vs. thermal mode vs. landing mode. If it doesn't need to change based on a switch, do it with Servo Travel instead of Dual Rates. If you are working on a V-Tail or Elevon model, then you would use Dual Rates to adjust the ratio between pitch and roll/yaw. Use Servo Travel to adjust the maximum amount in the highest position of the Dual Rates switch. -

An Investigation of the Effects of Flaperon Actuator Failure on Flight Maneuvers of a Supersonic Aircraft
Research Paper ISSN 2383-4986 International Journal of Aerospace System Engineering http://dx.doi.org/10.20910/IJASE.2016.3.2.1 Vo l . 3, No.2, pp.1-8 (2016) An Investigation of the Effects of Flaperon Actuator Failure on Flight Maneuvers of a Supersonic Aircraft Seyool Oh1†, Inje Cho1, Craig McLaughlin2 1Aircraft Research & Development Division, Korea Aerospace Industries, ltd, KOREA 2Dept. of Aerospace Engineering, The University of Kansas U.S.A. †E-mail:[email protected] Abstract The improvements in high performance and agility of modern fighter aircraft have led to improvements in survivability as well. Related to these performance increases are rapid response and adequate deflection of the control surfaces. Most control surface failures result from the failure of the actuator. Therefore, the failure and behavior of the actuators are essential to both combat aircraft survivability and maneuverability. In this study, we investigate the effects of flaperon actuator failure on flight maneuvers of a supersonic aircraft. The flight maneuvers were analyzed using six degrees of freedom (6DOF) simulations. This research will contribute to improvements in the reconfiguration of control surfaces and control allocation in flight control algorithms. This paper compares the results of these 6DOF simulations with the horizontal tail actuator failures analyzed previously. Key Words : Flaperon, Actuator failure, Flight maneuver, Supersonic aircraft , Combat aircraft only for specific flight phases. Primary control 1.
