A widely used material for lightning strike protection of CFRP structures within the aerospace industry is expanded metal foil (EMF). An issue with EMF is micro cracking of the paint, which can result in corrosion of the metal foil and subsequent loss of conductivity. Boeing researchers examined the issues of stress and displacement in the composite structure layup, which contribute to paint cracking caused by aircraft thermal cycling.

Since the 1960's, lightning protection of aircraft has been an important design aspect, a concern for the flying public, aircraft manufacturers and the Federal Aviation Administration (FAA). With the implementation of major aircraft structures fabricated from carbon fiber reinforced plastic (CFRP) materials, lightning protection has become a more complicated issue to solve. One widely used material for lightning strike protection of CFRP structures within the aerospace industry is expanded metal foil (EMF). EMF is currently used in both military and commercial passenger aircraft. An issue that has historically been an area of concern with EMF is micro cracking of paint on the composite structure which can result in corrosion of the metal foil and subsequent loss of conductivity. This paper addresses the issues of stress and displacement in the composite structure layup which contribute to paint cracking caused by aircraft thermal cycling. The analysis of EMF by computer modeling is made using commercially available COMSOL Multiphysics software that is supported by data from limited experimental testing.

The performance enhancement of a vertical tail provided by aerodynamic flow control could allow for the size of the tail to be reduced while maintaining similar control authority. Decreasing tail size would create a reduction in weight, drag, and fuel costs of the airplane. The application of synthetic jet actuators on improving the performance of the vertical tail was investigated by conducting experiments on 1/9th and 1/19th scale wind tunnel models (relative to a Boeing 767 tail) at Reynolds numbers of 700,000 and 350,000, respectively. Finite-span synthetic jets were placed slightly upstream of the rudder hinge-line in an attempt to reduce or even eliminate the flow separation that commences over the rudder when it was deflected to high angles. Global force measurements on the 1/9th scale model showed that the flow control is capable of increasing side force by a maximum of 0.11 (19%). The momentum coefficient that created this change was relatively small (Cμ = 0.124%). Furthermore, for some conditions, when the individual jet strength was held constant, reducing the spanwise density of active actuators (e.g., turning on every other or every fourth jet) results in more control authority relative to when all jets are on.

Over 1,200 large diameter holes must be drilled into the side-of-body join on a Boeing commercial aircraft's fuselage. The material stack-ups are multiple layers of primarily titanium and CFRP. Due to assembly constraints, the holes must be drilled for one-up-assembly (no disassembly for deburr). In order to improve productivity, reduce manual drilling processes and improve first-time hole quality, Boeing set out to automate the drilling process in their Side-of-Body join cell. Implementing an automated solution into existing assembly lines was complicated by the location of the target area, which is over 15 feet (4 meters) above the factory floor. The Side-of-Body Drilling machines (Figure 1) are capable of locating, drilling, measuring and fastening holes with less than 14 seconds devoted to non-drilling operations. Drilling capabilities provided for holes up to ¾″ in diameter through stacks over 4.5″ thick in a titanium/CFRP environment. Using high precision servo control, each layer could be customized with specific drill parameters optimized to improve hole quality and decrease drill cycle time.

The use of silane chemistries tailored to promote the adhesion of performance and appearance coatings to metal substrates are requiring new methodologies for measuring, approving, and implementing on commercial aircraft. Engineering performance, lean manufacturing, environmental and employee safety considerations are driving the commercial aerospace industry to replace long standing conversion coating materials and processes. Tailored silane chemistries such as Boegel are being considered for many of these applications. Silanes work by reacting with metal oxides providing a strong covalent bond, cross linking to form a tough barrier and have an organic functional group tailored to react with the specific resin system in the subsequent coating. Traditionally conversion coatings such as anodize and chromate conversion coating performance is validated based on meeting standalone requirements. Since tailored silanes are optimized to enhance adhesion, they rely on the subsequent coatings to provide corrosion protection; the overall performance is based on the entire coating system and not standalone characteristics.
