Abstract Few work concerned on the flexural strength of carbon fiber reinforced plastic (CFRP)-aluminum fuselage frames with bolted splice joints used in aeronautical industry. To provide help for design CFRP aircraft strcutures, this paper investigated behavior CFRP-aluminum experimentally. Firstly, were fabricated mid-span joints. The comprised: or unreinforced aluminum plates to frames. bolt...

The main acoustic noise source of helicopters is supposed to be the rotor blades, but scattering effect helicopter fuselage sometimes cannot ignored. For accuracy prediction and research on affections fuselage, an FWH–BEM Method (FBM) based convective FW–H equation boundary element method (BEM) presented for effects approach calculation a helicopter’s field. In this paper, different models are ...

We report the results of an experimental comparison of airplane boarding methods. This test was conducted in a mock Boeing 757 fuselage, located on a Southern California soundstage, with 12 rows of six seats and a single aisle. Five methods were tested using 72 passengers of various ages. We found a significant reduction in the boarding times of optimized methods over traditional methods. These...

The influence of corrosion on ultrasonic and electromagnetic nondestructive evaluation results has been simulated for 2-layer aluminum aircraft fuselage. Simulations have been performed with respect to ultrasonic time-of-flight measurements aiming on the detection of corrosion at the backwall of the first aluminum layer. Calculations of the eddy current probe response have been performed, where...

The aerodynamic interaction between the rotor and fuselage is an important consideration in relation to drag performance prediction of helicopters. In this paper, based on dynamic patched-grid technology coupled with a three-dimensional N–S equation solver, numerical study effects flow field light civil helicopter carried out under forward flight condition. deterioration evolution structure cau...

The fuselage surface pressure fluctuations on an Airbus-A320 aircraft at cruise conditions are simulated by solving a Poisson equation. right-hand-side source terms of the equation, inc...
