Airplane Pitch Response To Rapid Configuration Change: Flight Test And Safety Assessment, Ralph Kimberlin, Markus Wilde, Brian Kish, Isaac Silver
Airplane Pitch Response To Rapid Configuration Change: Flight Test And Safety Assessment, Ralph Kimberlin, Markus Wilde, Brian Kish, Isaac Silver
Journal of Aviation Technology and Engineering
This paper examines airplane response to rapid flap extension on seven general aviation airplanes. The scenario involves a pilot flying in the traffic pattern becoming distracted, abruptly extending flaps while looking outside the airplane, and failing to notice airspeed and pitch-attitude changes. The airplanes tested reached pitch forces of up to 36 lbf, meeting FAA requirements but exceeding the capability of 55% of the population. Flight data showed a pitch-up to more than 30˚ in 5 s after flap extension, causing airspeed to drop below stall speed for four of the airplanes. At traffic pattern altitudes, stalling an airplane can …
Can The Timeframe Of Reported Uas Sightings Help Regulators?, Spencer Erik Pitcher, Kelly A. Whealan-George
Can The Timeframe Of Reported Uas Sightings Help Regulators?, Spencer Erik Pitcher, Kelly A. Whealan-George
Beyond: Undergraduate Research Journal
Remotely controlled small aircraft, otherwise known as Unmanned Aircraft Systems (UAS) or drones have started to impact the United States National Airspace System by interfering with the safe flight of aircraft. As the UAS industry continues its expected growth into the future, lawmakers, as well as regulators at the Federal Aviation Administration (FAA) and the aviation community must be able to predict when there will be more UAS craft in the air that could cause an interruption to air traffic so that more resources can be allocated optimally to counter the threat of UAS craft. The purpose of this study …
Tooling Design Modeling For Composite Fuselage Of Beechcraft King Air 250 Using Catia, Miazor Fidelis Ekom
Tooling Design Modeling For Composite Fuselage Of Beechcraft King Air 250 Using Catia, Miazor Fidelis Ekom
Journal of Aviation Technology and Engineering
Aircraft’s constant operation in tough conditions necessitates the need for structural components of high strength yet low weight. Composite materials are being used as an alternative to conventional aluminum alloys because of their competitive strength-to-weight and stiffness-to-weight ratios. In this paper, the detailed design procedure of a light-aircraft composite material fuselage tooling in three dimensions is shown. In its operation, the layup tools provide a surface for the composite part which is the correct shape of the part and is stable through the cure cycle, and also providing a means of indexing the part for the next manufacturing operation. This …
Comparative Study On The Prediction Of Aerodynamic Characteristics Of Mini - Unmanned Aerial Vehicle With Turbulence Models, Somashekar V, Immanuel Selwyn Raj A
Comparative Study On The Prediction Of Aerodynamic Characteristics Of Mini - Unmanned Aerial Vehicle With Turbulence Models, Somashekar V, Immanuel Selwyn Raj A
International Journal of Aviation, Aeronautics, and Aerospace
When dealing with CFD simulations the turbulent nature is seen on most of the engineering flows and these flows need to be solved. Reliable and applicable CFD outputs can be obtained from the accurate modelling of the turbulence as it is one of the most vital elements of CFD modelling. The RANS equations are extensively employed to analyse the complex flows over aircraft and for this purpose, a turbulence model is needed for turbulent flow analyses. Compatible turbulence must be chosen for the exact predictions of aircraft aerodynamic characteristics. In this report, numerical analyses of Mini-UAV are done to compare …
Internet Of Things 36-Rotor Multicopter For Ionizing Radiation Surveying, Svetoslav Zabunov, Garo Mardirossian, Rositsa Miteva, Todor Kunchev
Internet Of Things 36-Rotor Multicopter For Ionizing Radiation Surveying, Svetoslav Zabunov, Garo Mardirossian, Rositsa Miteva, Todor Kunchev
International Journal of Aviation, Aeronautics, and Aerospace
This paper presents an Internet of things 36-rotor unmanned aerial vehicle suitable for radiological surveying of buildings and facilities. The design of the 36-rotor multicopter platform is disclosed. The aircraft is used as a testbed for a lightweight gamma/beta/neutron ionizing radiation sensor closely coupled with the autopilot of the multirotor aircraft. A prototype of the drone and sensor was developed and initial tests were conducted. Test results are presented with data from measuring different radiation sources. The proposed novel design is compared to existing work and advantages to the latter were established.

International Journal of Aviation, Aeronautics, and Aerospace
Aircrafts are one of the most important means of transportation today. For aircrafts to be able to serve safely, their maintenance must be done in a timely and complete manner. In addition to regular maintenance, it may appear suddenly; there is also irregular maintenance performed in cases such as lightning strikes, bird strikes, and hard landings. Engine failures and maintenance has great importance in aircraft maintenance. Using the data recorded during the flight by flight data recorder, the engine health condition is monitored and the necessary maintenance procedures are carried out. In this study, the exhaust gas temperature was estimated …

As in countless other fields of human endeavor, small unmanned aircraft systems (sUAS) have the potential to benefit pinniped (Pinnipedia; e.g., Phocidae [seals], Otariidae [sea lions], and Odobenidae [walruses]) response efforts. The employment of sUAS could give responders a close-up look at animals in distress in order to determine their condition as well as develop a response strategy. However, unlike other subjects that are regularly inspected by sUAS (e.g., croplands and civil infrastructure) pinnipeds may respond to the distinctive sound generated by small, multirotor sUAS. This reaction may include retreating into the water en masse, which could put …

The drone industry yearns for enhanced aerodynamic performance. In order to achieve this feat, researchers and engineers are trying to mimic the natural flyers due to their aerodynamic optimality. One such flyer, the Albatross is an inspiration for many marine drones due to its planform and aerodynamic efficiency. The wing of the plan form is designed and simulated to study its properties. The Bell-Shaped Lift Distribution is incorporated for higher efficiency and elimination of the total downwash produced in case of an Elliptical Lift Distribution. A blended wing body inspired by the Falcon is used for smoother airflow interactions. Furthermore, …
