Questions related to Flight Simulation
I want to run an experiment with pilots flying a simulated flight. I need to collect data about their performance (accuracy of handling the joystick, speed etc). Do you know if there is a flight simulation game that allows the experimenter to collect such kind of data?
Thanks a lot,
Alex
I have created a 2 dimensional mathematical model for a UAV in matlab. I also created a programmatic GUI for the UAV flight simulation. However, i now need to create a clock which displays the time for the flight of the UAV. How can i do this
I am study aircraft fly in the air,simulating body and rudder roll in 3D . I need dynamic mesh.As presented in ppt,the rudder rotate in the face perpendicular to the face body rotating.Now,I don't konw how to make udf for the dynamic mesh.Please help.
I am trying to model a forward flight simulation for a hexacopter system. What is the most efficient boundary condition and unbounded flow domain for this kind of simulation?
I am currently designing a tiltwing aircraft. Designed in solidworks and remodeled in X-plane flight simulator for flight tests. During transition flights from hover to forward flights I am experiencing sudden uncontrollable nose-down pitching moments from which the aircraft cannot recover. Upon certain intuitive improvements such as increasing engine power, full transition is now possible, at a very high sink rate, which eventually ends up in a crash. I cannot increase power indefinitely, i also cannot increase wing area indefinitely.
Are there any other parameters which can be adjusted and does the wing tiltrate also affect the transition. My wing tiltrate in 8 degrees per second. I increased it to 14, still the same problem, with an earlier stall.
Data Set Out table line 21, in the X-Plane Flight Simulator, Vx,Vy and Vz velocities are shown. And, these velocities are given at inertial frame, but i want to take body frame linear velocities.
I’m just analyzing sidestick inputs from a flight simulator study with manual flying (raw data). On Airbus aircraft you can either do one-dimensional/separate or two-dimensional/combined inputs on the two-dimensional sidestick.
Some flight trainers say that a pilot should separate the inputs on both axes, doing only one-dimensional inputs, i.e. pitch or roll inputs, but not at the same time. One possible reason for separating both axes might be a higher control accuracy when manipulation one axis only.
I’m looking for documents, reasons, literature for or against this practice. Does anyone know such documents or know some reasons for or against the separation of axes?
I would like to control multiple UAV simultaneously to generate patterns like Intel did at the Olympics opening ceremony and here:
Do you know if some kind of library exists that would help to program such simultaneous flight paths? Given a spatial geometric configuration of the UAV, the library should help generate the trajectories (collision free) needed to bring each UAV into position.
Any reference, book or research paper about this topic is also welcome!
Thanks!
disadvantage of using dc brushless motors.
disadvantage of using hydraulic system for control loading system of flight simulator.
I found very inconsistent suggested numbers during research: from 500 Hz, most in 2-4 kHz range, some as high as 500 kHz.
My available servo controller is capable of 2 kHz velocity/position control loop. Is this enough for a realistic control stick force simulation?
Thank you!
I am planning to do work with Supersonic nozzle design with Jet Vane Thrust Vector Control in Supersonic Fighter Aircraft. I would like to know if it is possible to implement Jet Vane TVC in Supersonic Fighter Aircrafts. Main aim is to increase in maneuverability by this work.Which Method will be suitable to perform this work Computational(CFD) or Experimental. And i need to analyse the erosion phenomena of Jet Vane . Suggest and drop your queries. Please help me to get some journal papers related to this.
I´m trying to model the SH60 (sea hawk helicopter) on FLIGHTLAB, but the paper "PROCEDURAL GUIDE FOR MODELING AND ANALYZING THE FLIGHT DYNAMICS OF THE SH-60B HELICOPTER USING FLIGHTLAB" from Roy C. Wagner has some missing information about horizontal stabilizer tables. Is there somebody who can help me to find it?
Many models of this aircraft were developed, does somebody know a source for geometrical, aerodynamic, and mass characteristics?
I am trying to think of simple general modifications that can be done to a conventional type UAV so that it flies with better stability during crosswind of about 13m/s.
Is there any reliable simulation method or tool for spin recovery of Light Aircraft or general aviation?
Any suggestion for spin analysis?
Real aircraft is too large and when i use similar parameters then, i can't simulate the flow for large velocities in wind tunnel. Is there a way to simulate high velocities in wind tunnel.
My research topic is bird flight simulation. how could I validate my results? pls suggest me some journal or paper regarding bird flight.
THANK YOU
Are the satellite pictures and DEM used in new flight simulators?
Which engine is used in this method(cryengine …)?
I’m analyzing pilots’ control input and resulting flight performance (flight path) data in a simulated manually flown ILS approach. We had Airbus flight simulators that means sidesticks. I’m looking for the influence of practice on the applied control behavior. I guess that this control behavior can be matched to different control strategies.
I’ll do the following analyses:
1. To which amount of time did a pilot no input / input on one axis / input on both axes?
2. Is the mean value of all inputs higher or lower than the standard deviation (M>SD, M<SD)? Here I would match strategies to control behavior: M>SD “optimizing strategy”, M<SD “steady hand”. I derived this approach from “Variance as a Method for Objectively Assessing Pilot Performance” (Christopher K. McClernon, James C. Miller, and James C. Christensen. Proceedings of the Human Factors and Ergonomics Society Annual Meeting, September 2012; vol. 56, 1: pp. 85-89. )
Has anybody already done such analyses, comments, literature, ideas or anything else?
How to obtain force vs displacement curve (Hysteresis graph) for a control loading system??? I am making a control loading system for a reversible flight control system. Please give your valuable suggestions about the same.
Dear Sir/Madam,
Can anyone give advice on CFD validation cases for airships? We are developing airships about 50 meters long. CFD simulation is heavily used for providing data for performance and control/stability analysis.
Thanks

How can the propeller slipstream-induced yawing effect on a General Aviation aircraft be estimated with only limited geometric information available?
Any references to existing literature dealing with this would be helpful.
Using stereovision camera in uav navigation.How can it can create a navigation waypoint
For finding transfer function of aircraft we are finding 6 equations of motions then longitudinal and lateral equations of motions then linearization then statespace matrix then transfer function and used it in closed loop system
if we take a similar transfer function fraction equation as numerator and denominator of our own and use it in closed loop system
i mean to ask that if we take similar fraction or transfer function then simulate it in matlab the if we getting the approximate results when compared with original transfer function, then what is the use of dynamics why we working very hard for dynamics of aircraft and uav or quadrotor? is it just for sake of proof?but i think main thing is to design different controllers like linear and nonlinear controllers?
I am working on improving cockpit automation interfaces and will be using a PC based simulation as part of that effort. I am considering using Microsoft’s FSX, Flight Gear, X-Plane or Prepar3D. I’m leaning toward Flight Gear as it is open source and may be easier to develop interfaces with it using custom software. I wanted to ask other researchers what opinion they have regarding the suitability of these platforms for academic research especially when failure simulations will be created?
I have to design a wing for a UAV. The wing should measure 3 mt.
I've read about control strategies and simulation methods and found these 3 simulations the same:
Model-in-the-loop = Rapid Control Prototyping = Software simulation?
Is there any difference?
What are the main characteristics of each?
What kind of research is going on in the field of aeromodelling and aircraft designing? Are there papers that publish only computer simulated results in this field?
What is the scope of research with unmanned aircrafts designing and improvements?
