Distributed Dynamic Load Identification on Irregular Planar Structures Using Subregion Interpolation

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (2)

Spatially distributed load on aircraft structures is difficult to obtain due to the limitation of measurement technology, the complexity of load and t......

Trimming Analysis Method of Quad Tilt Rotor Based on Aerodynamic Interference Model

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (2)

The quad tilt rotor (QTR) has complex aerodynamic characteristics and strong aerodynamic interference. The flight dynamic model is the basis of contro......

Aeromechanical Stability of a Bearingless Rotor Helicopter with Double-Swept Blades

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (2)

The rotor blade double-swept-tip geometry can effectively improve the aerodynamic and aeroacoustic behaviors of a rotor. However, the aeroelastic or a......

Mathematical Expression of Geometric Relationship in Osculating-Cone Waverider Design

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (4)

Waveriders have a high lift-to-drag ratio in hypersonic states, while the flexibility of design methods must still be improved because of some deficie......

Development and Analysis of Variable Pitch Propeller with Aerodynamic Stable Blades

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (2)

For small short/vertical takeoff and landing (S/VTOL) unmanned aerial vehicles, the propeller design should reach a compromise between S/VTOL and crui......

Risk and Economic Evaluation of Aircraft Program Based on Monte Carlo Simulation

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (4)

The commercial aircraft development program is generally confronted with huge risks from various aspects. To improve the economic benefits of the airc......

Increment Frictional Loading Analysis for High-Lift Devices with Seals

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (2)

To ensure the aerodynamic performance of the slat in aircraft when retracted, it is necessary to set rubber seals in the seam between the leading-edge......

Effect of Initial Pitching Angle on Helicopter Ditching Characteristics Using Smoothed-Particle-Hydrodynamics Method

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (1)

The present Paper investigates the ditching characteristics of a helicopter model by means of an in-house-developed smoothed-particle-hydrodynamics so......

Numerical Virtual Flight Simulation of Quasi-Cobra Maneuver of a Fighter Aircraft

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (1)

By using a computational-fluid-dynamics-based numerical virtual flight (NVF) simulator, a simplified quasi-Cobra maneuver of a typical third-generatio......

Dynamics Analysis of Spatial Landing-Gear Mechanism with Hinge Clearance and Axis Deviation

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (1)

The hinge clearance and rotation axis deviation of aircraft landing-gear retraction mechanism are unavoidable due to factors, such as manufacture, ass......

Three-Dimensional Strains on Twisted and Swept Composite Rotor Blades in Vacuum

期刊: JOURNAL OF AIRCRAFT, 2021; 58 (1)

This paper presents an investigation of the effects of tip sweep on highly twisted composite rotor blades by acquiring strain data in vacuum. Three pa......

Perturbation Analysis and Control of Mach Number 2.4-Meter Transonic Wind Tunnel

期刊: JOURNAL OF AIRCRAFT, 2020; 57 (6)
