1. NASA Juncture Flow Computational Fluid Dynamics Validation Experiment.

Author

Rumsey, Christopher L., Ahmad, Nashat N., Carlson, Jan-Renee, Kegerise, Michael A., Neuhart, Dan H., Hannon, Judith A., Jenkins, Luther N., Chung-Sheng Yao, Balakumar, Ponnampalam, Gildersleeve, Samantha, Bartram, Scott M., Pulliam, Thomas H., Olsen, Michael E., and Spalart, Philippe R.

Abstract

The purpose of the NASA Juncture Flow experiment was to acquire high-quality flowfield details deep in the corner of a wing-body junction specifically for the purpose of computational fluid dynamics (CFD) validation. A truncated DLR F6 wing was used along with a flat-sided fuselage with windows that allowed both laser Doppler velocimetry and particle image velocimetry measurements to be made very close to the corner. This paper describes the experiment and its results. It also makes comparisons between the wind-tunnel data and Reynolds-averaged Navier-Stokes CFD results using a new version of a quadratic constitutive relation that was recently developed to improve separated corner-flow predictions. This validation experiment provides useful flowfield data that can be used to test the ability of CFD methods and models to accurately represent separated juncture flow physics.

2. Transient Aeroelastic Response of a Rotor During Rotor Speed Transition in Forward Flight.

Author

Dong Han and Barakos, George N.

Abstract

Compound helicopters often have to reduce their rotor tip speeds to achieve higher forward speeds. The rotors, therefore, have to undergo a transient process of rotor speed changes. To investigate the transient loads and the related transformation from the rotating frame to the nonrotating frame, a rotor model is used to predict the transient aeroelastic responses. The rotor model is validated by using test data of a teetering model rotor during engagement and disengagement operations. The investigations indicate that a small transient lagwise root bending moment can result in a large transient contribution to rotor torque. This transient component is triggered by the force related with the sudden change of the angular acceleration of the rotor speed. Increasing the blade damping in the lagwise direction can significantly decrease the transient components of the lagwise root bending moment and the corresponding rotor torque. Making the angular acceleration continuous will not trigger the transient components, suggesting that this is a better way for the reduction of the transient rotor loads during speed changes.

3. Lamination Parameter-Based Two-Dimension Sampling Optimization Method for Stacking Sequence Design of Composite Laminates.

Author

Zhao Jing

Abstract

A novel two-dimension sampling optimization method (2DSO) is proposed for the stacking sequence design of composite laminates. The concept of using lamination parameters (LPs) to characterize distances of different stacking sequences is introduced. The first step involves using the boundary vertices and boundary lines of the LPs to yield randomly and uniformly distributed continuous variables in the LP design space. In the second step, stacking sequences are generated randomly and evaluated with a dynamic distance constraint to ensure their LPs are close to previous continuous variables. Following this, objective values are computed for these feasible points; and several best point candidates are identified. Next, the local sampling optimization is performed by generating new stacking sequences in the vicinity of the aforementioned best point candidates. The preceding two steps are repeated until the best objective converges. Lastly, a sequential permutation search (SPS) serves as a local optimization solver to target the global optimum. Because design optimization is always conducted in the stacking sequence design domain and the LP is employed to measure the distances of distinct stacking sequences and ensure uniform distribution of initial points, no feasible constraint is needed for LP; therefore, the optimal vortices are captured efficiently. The 2DSO method is used to optimize the fundamental frequency and buckling load of composite plates and shells, and the results are compared to a layerwise optimization approach (LOA), the SPS, and a genetic algorithm (GA). The results demonstrate that 2DSO outperforms LOA and SPS, and it has similar robustness to GA while being significantly more efficient. [ABSTRACT FROM AUTHOR]

4. Active Vibration Control of Helicopter Fuselage with Large Dynamic Modeling Errors.

Author

Lang Kai, Shang Lina, and Xia Pinqi

Abstract

Active vibration control is an effective method for vibration control of a helicopter fuselage. However, when there are large dynamic modeling errors of a control system, the effectiveness of active vibration control may decrease, or even the control may diverge by using the existing harmonic control algorithms. Large modeling errors will result in inaccurate frequency response functions in the control system. In this paper, a new frequency response function updating-harmonic identification algorithm and its convergence condition have been proposed for effective active vibration control of a helicopter fuselage with large modeling errors through identifying the frequency response function of the control system in real time. In addition, to improve the accuracy of identifying frequency response function and further improve the effect of active vibration control, a dynamic harmonic control weight matrix algorithm is also proposed in this paper. The active vibration control simulations and experimental validation on a dynamically similar and geometrically scaled structure of a helicopter fuselage verify that the proposed algorithm in this paper can achieve faster speed of convergence and better effect of vibration control when there are large dynamic modeling errors over the existing harmonic control algorithms.

5. Pressure Gradient Effects on the Performance of Riblets Installed on Aircraft Surfaces.

Author

Monami Sasamori, Seigo Koga, and Mitsuru Kurita

Abstract

A method for estimating the drag reduction performance of riblets installed on the surfaces of an aircraft was extended to take the effect of the pressure gradient over the aircraft into account. This method simply and roughly estimates the effectiveness of riblets applied to arbitrary surfaces of any aircraft by fusing wind tunnel test data and computational fluid dynamics analysis. The drag reduction rate is calculated from the relationships between friction drag reduction DR, wall-normalized riblet spacing s+, and Clauser pressure gradient parameter β. To obtain this relationship, a wind tunnel test with straight riblets in an adverse pressure gradient was carried out. The resulting shift in the value in the intercept of the log-law region of the mean velocity profile for riblet cases indicates that the drag reduction effect decreases as the Clauser parameter β increases. Based on these results, an approximate surface for the relationship between DR, s+, and β was proposed, and the drag reduction performance of riblets installed on the surfaces of a conceptual aircraft was estimated. The total drag reduction rates estimated by the extended method considering pressure gradient effects and the original method case were both about 2%, which indicates that the effects of the pressure gradient on the aircraft on overall riblet performance are small.

12. Simultaneous design of a stiffened fuselage panel and number of structural tests 'Code 98243'

Author

Usta, R.C., Acar, E., Usta, R.C., and Acar, E.

Abstract

54th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference -- 8 April 2013 through 11 April 2013-Boston, MA-98243, Reliability-based sizing optimization of a stiffened fuselage panel together with the numbers of coupon and element tests is performed for minimum lifecycle cost. The probability of passing certification test is used as the measure of reliability. Certification test evaluates the capability of the panel to sustain a two bay skin crack with broken central stiffener under ultimate load. Uncertainty in the fracture toughness prediction, variability due to the finite number of coupon tests, and uncertainties in geometry and loading conditions are studied. The effects of structural element tests on reliability are evaluated through Bayesian updating of the fracture toughness distribution. It is found that the number of coupon tests is only marginally sensitive to the weight penalty parameter, while the number of element tests is strongly dependent on it. If the weight penalty parameter increases, each pound of structural weight becomes more valuable, the designer tend to increase the additional knockdown factors to save weight and the number of element tests increases to compensate for the increased knockdown factor. © 2012 AIAA.
