This document provides an overview of computational methods for analyzing bird strikes on aircraft structures. It begins with a literature review surveying over 190 papers on bird strike modeling dating back to 1968. Three main modeling approaches are discussed: Lagrangian, Eulerian, and smoothed particle hydrodynamics (SPH) formulation. The document concludes that while no single approach is accepted, computational simulations are increasingly used to certify aircraft structures in place of physical tests, though validation with test data is still required.

Flight Safety Case Study: Adi Sucipto Airport Jogjakarta - IndonesiaIRJESJOURNAL
Abstract: Adi Sucipto Airport-Jogyakarta is an airport with enclave civil status or as TNI-AU airbase (civilian airport within the military area) has limited infrastructure with Azimuth Runway 09-27, has no RESA (Runway End Safety Area). The calculation results using Acceptable Safety Level (ASL) standard 1 x 10-7 shows that the probability of accident risk at wet runway condition is greater than in dry condition. Runway Excursion occurs at the airport, especially when the runway is wet and overrun due to hydroplaning and the plane deviates from the center of runway as well as the aircraft wheels are in contact with ground or obstacle surface outside the runway. It means the thicker layer of water above the runway will cause increased risk of accidents on the runway. This is why standing water should be immediately removed from the runway as quickly as possible. Mitigation efforts need to be done simultaneously with recovery by adding RESA and other preventive efforts in order to water patch and standing water does not exceed 2 mm and apply the mandatory of SOP consistently at the airport.

DESIGN AND ANALYSIS OF AN ACTIVE TWIST ROTOR BLADES WITH D-SPAR MODEL USING C...AM Publications
Today’s helicopters are the result of collaborative work in mechanical engineering and aeronautics. A helicopter main rotor or rotor system is the combination of a rotary wing and a control system that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. In the field of rotorcraft, the research in this project is currently focusing on active blade systems to adapt the aerodynamic properties of the blade to the local aerodynamic conditions. Fuel-efficiency, reduction of vibration and noise and increase of the helicopter maximum speed are the benefits expected from these new technologies. A helicopter's rotor is generally made of two or more rotor blades. Rotor blades are made out of various materials, including aluminum, composite structure, and steel or titanium, with abrasion shields along the leading edge. The blade pitch is typically controlled by a swash plate connected to the helicopter flight controls. An Active Twist Rotor (ATR) is developed for future implementation of the individual blade control for vibration and noise reduction in helicopters. The rotor blade is integrally twisted by direct strain actuation using active fiber composites (AFC). In this thesis, the model of rotor blade is designed and analyzed. 3D models are done in CATIA. Analysis is done in Ansys. The materials used for original model are steel and Aluminum alloy, The modified model is analyzed by specifying aluminum alloy using solid element and also the shell element. The optimization results have been obtained for design solutions, connected with the application of active materials.

Airlines Study Alternatives to Jets’ Black Boxes
By CHRISTINE NEGRONI
Modern communication technology allows even those with little important to say to transmit real-time information about where they are and what they are doing. But last month, when Airbus jets from Air France and Yemenia Airways crashed into the ocean, taking their black boxes into the deep with them, neither aircraft could send its data and cockpit voice recordings to a secure place on the ground.
On July 2, the day that the missing recorders from Air France Flight 447 were presumed to have exhausted their 30-day battery and stopped emitting the pinging noise of the locator beacon, Airbus announced that it would look for new ways to reduce the chance of losing critical data.
“This is a worldwide industry issue, albeit a rare one,” said Mary Anne Greczyn, manager of communications for Airbus Americas. In an e-mail message, Ms. Greczyn said, “Recent accidents certainly made this a front-burner topic of discussion.”
What is known so far about the crash of Flight 447, in which 228 people died, comes from automatic messages sent from the airplane to Air France. Those messages are not intended to provide information for accident investigators but are routinely used by airlines for maintenance. When an airplane is crossing an ocean and out of radio range, only the most important information is sent, since communication must be by satellite and transmission is expensive. Airlines can select what kind of flight data is worth the price of satellite time.
According to a statement from Airbus, even using the normal radio signal to send all the information about a flight would require enormous bandwidth.
But Krishna Kavi, a professor of computer science and engineering at the University of North Texas, said that might not be the case. In 2001, Mr. Kavi proposed transmitting in real time just the information from the flight data recorder. “The amount of data is very small compared to video photos that you receive on smartphones,” he said. Mr. Kavi said his plan was even more achievable today.
Mike Poole, an air crash investigator with CAE Flightscape, an aviation safety company in Canada, said that transmitting all that data in real time “sounds really attractive” but ...
TESTING OF COMPOSITE ON DROP-WEIGHT IMPACT TESTING AND DAMAGE IDENTIFICATION ...AM Publications
In recent years the use of composite materials in structural components has become increasingly common in a wide range of engineering applications. Composite materials offer numerous advantages over more conventional materials because of their superior specific properties, but a serious obstacle to a more widespread use of these materials is their high sensitivity to localized impact loading. This paper presents an experimental study to assess the impact response of drop weight impact tests on fiber reinforced polymer composites with deferent load and damage identification of composite using Non-destructive testing techniques ultrasonic testing (UT) C scan. In the study includes checking the strength of the specimen, plotting of graphs between the height and the impact energy obtained and tabulating the results after conducting the various functional tests.
CFD ANALYSISOF UNMANNED COMBAT AERIAL VEHICLE (UCAV) BY VARYING ANGLE OF ATTACKAM Publications
Using CATIA V5 design software a model was designed on the platform of Unmanned Combat Aerial Vehicle (UCAV).Computational Fluid Dynamics (CFD) Analysis was performed on the ANSYS Workbench 14.0(Fluent) of the UCAV. The Design was particularly done for low speed and high Angle of Attack (AOA) criteria. Important results were interpreted such as lift, drag and lift to drag ratio for various AOA which eventually leads to determining stall angle of the UCAV. Primitively stall angle of the UCAV is found to be 30 degrees and the lift to drag ratio as 7.63, thus making UCAV to have high stall angle at lower speeds. 100-120m/s are taken for lower speed phenomena, density of air being constant at 1.22 kg/m3.
FE Based Crash Simulation of Belly Landing of a Light Transport AircraftRSIS International
Crash survivability is one of the key features to be
attended during the design of an airworthy aircraft. Belly/crash
landing is the most common phenomenon to be considered in
developing a crashworthy product. That makes it essential to
have redundant structure to enhance the safety of occupants and
also limit the damage to easily repairable state in case of such
event. Even from the certification point of view, it is necessary to
investigate this event by test/analysis. Recent development of
advance computing and their capability to simulate such
phenomenon to acceptable accuracy under given conditions
conveniently replace the need for test which is otherwise costly.
At the same time, one has to be cautious while selecting the
modeling parameters to simulate the condition near to reality.
Taking advantage of this feature an effort is made to simulate the
belly landing and its consequences on the structure complying to
the guidelines of the federal aviation regulations. This paper
presents the methodology adopted to successfully simulate the
belly landing phenomenon for a light transport aircraft flying
prototype.
Flight safety is the key focus of the activities of all aircraft enterprises and civil
aviation institutions. One related risk factor is a lack or untimely receipt or use of
outdated versions of the required information on regulation of the civil aircraft
operating processes. For this reason, information support is the increasing focus of
all aspects of the aviation services sector.
Establishment of the civil aviation regulatory and guidance library is among the
main means for providing information and library support in this area.
DETECTION OF DAMAGE IN STIFFENERS OF AIRCRAFT WING STRUCTURE BASED ON INDUCED...IAEME Publication
In this paper, the technique of structure health monitoring was applied to detect damage occurrence in the stiffeners of wing structure. A wing structure of airfoil shape according to digital NACA 0015 was considered for modelling the aerodynamic wing shape. Finite element models of the wing structure were created included undamaged and damage wing structures using high order eight nodes and six nodes shell elements. The damaged wing models included damaged at the main spar at 20%, 40%,60% and 80% the distance than the root chord. A mathematical model was developed using high order shell elements and programmed via MATLAB. The load cases were predicted experimentally using wind tunnel test on a wood airfoil prototype such that the pressure distributions through upper and lower wing skins measured at different attack angles.
