This paper discusses the conceptual design of a hybrid thin haul air taxi. It presents a design methodology for a distributed propulsive hybrid aircraft highlighting the differences in design procedures between conventional design and hybrid distributed propulsion design. In addition, it demonstrates the impact of both hybridization and distributed propulsion on the reduction of direct operating cost for operators. The aim of the design is to offer a better alternative aircraft to serve the emerging new market of scheduled thin haul aircrafts.


Design and performance evaluation of a fuel filter
Ayrancı, Hakan; Albayrak, Kahraman; Department of Mechanical Engineering (2010)
This thesis analyzes design criteria’s, performance evaluation of fuel filter. Fundamental concepts, definition and systems has been discussed at literature survey parts. Fundamentals of filter design tests and calculations are discussed. In Addition Frequency and amplitude effect on fuel filter efficiency investigated with different particle sizes by preparing special test set up. Test results has been analyzed by using Regression, Anova and Analyze of Variance methods with Minitab software.
Design of smart controllers for hybrid electric vehicles
Özen, Ekin; Dölen, Melik; Department of Mechanical Engineering (2005)
This thesis focuses on the feasibility of designing a commercial hybrid electric vehicle (HEV). In this work, relevant system models are developed for the vehicle including powertrain, braking system, electrical machines and battery. Based on these models ten different HEV configurations are assembled for detailed assessment of fuel consumption. This thesis also proposes a smart power management strategy which could be applied to any kind of HEV configuration. The suggested expert system deals with the exte...
Analysis and Design of Passive and Active Interconnected Hydro Pneumatic Suspension Systems in Roll Plane
Sağlam, Ferhat; Ünlüsoy, Yavuz Samim (2015-05-19)
In this study, analysis and design of a half car model in roll plane with passive and active unconnected and interconnected Hydro-Pneumatic (HP) suspension systems are made. An interconnection configuration with a connection between the piston side oil volume and rod side oil volume of the right and left suspensions, respectively, is considered. The performance of the active unconnected HP and interconnected HP suspension systems are compared in terms of ride comfort and handling. Nonlinear mathematical mod...

This paper presents the results of experimental work on flywheel energy storage systems for city buses. An efficient electronic hardware scheme is used to start the flywheel and traction machines. This scheme has been designed, fabricated and tested in our laboratory. A low frequency a.c. has been derived from an inverter fed from a three-phase uncontrolled rectifier to start the commutatorless d.c. motors. Commutation is achieved by using a capacitor and two auxiliary thyristors, whose ratings could be a f...
Performance evaluation of a wind driven DOIG using a hybrid model
Cadirci, I; Ermiş, Muammer (1998-06-01)
This paper presents the performance analysis of a wind driven double output induction generator (DOIG) operating at varying shaft speeds. A periodic transient state analysis of DOIG equipped with two controlled converters is carried out using a hybrid induction machine model. It is shown that practical aspects of converters such as overlap and harmonics reduce the power output of the DOIG system and limit the operating shaft speed range, especially in the subsynchronous region near the synchronous speed. Va...
