Manufacturing aerospace components is not easy. It requires the right technology and the necessary skills. Depending on the application and the materials used, the process for manufacturing aircraft parts vary.

One common method is the CNC machining part. In this method, the material used to make the aerospace parts is plastic. The CNC machine is used to cut out a piece of material from the entire work piece. Many kinds of CNC machines are used.

In CNC turning, the part is revolved around a lathe and is cut by a device that moves along. In CNC milling, the rotating cutter does the job of cutting the piece. There is also the Jig boring, which is a type of high-precision vertical milling. If pulling or pushing a cutter is involved, broaching is what you call the process. The broach is a linear cutting tool having many teeth.

All the machines today are controlled by a computer which feeds on a tape fit for a specific part. This machine saves time and makes possible swift machining of shapes that are complex and previously done by forging, casting and assemblage of many parts.

The Sheet metal spinning is another process of manufacturing aerospace components. Sheet metal spinning is already called ancient. Its counterpart today is flow turning. In flow turning, the work piece, such as a flat disc, is forced by rollers controlled by computer to shape around a mandrel.

A mandrel is a revolving die located on the center of the rollers. With this method, it is possible to produce shapes like conical or cylindrical with no joint.

In aerospace grinding, the cutting of parts is initiated by millions of very hard particles which are projected in a microscope from the surface of a drum or a wheel. There is also called electrolytic grinding which has the wheel powered by electricity. Here, the work piece is submerged into a container filled with electrolyte.

The revolving wheel does not make contact with the work piece, but definitely eradicates the small particles by electrochemical reaction. Then, the revolving wheel takes out the by-products which hinder the reaction.

Aerospace pressings are among the traditional techniques of shaping aircraft parts. In this process, the parts are shaped from sheet metal. To do this, the high-strength metals such as the ones used in gas turbines are pressed at high temperature. During this time, the metal warps, springs back, twists or deforms, and thus, handwork is needed to make the appropriate shape.

One type of isothermal presswork that is done is using heated dies of ceramic and of metal as they continuously produce correct stress-free shapes. There is also the process of hot blow forming to achieve better by products. Here, the sheet metal is forced into a die at high argon pressure using microprocessor control to keep the proper strain-rate. The argon is among the inert gases that never reacts with metals even in their melted state.

Certainly, with today’s modern technology, it is possible to create shapes that best fit aerospace components.

Steven F. Udvar-Hazy Center: Grumman F6F-3 Hellcat

Quoting Smithsonian National Air and Space Museum | Grumman F6F-3 Hellcat:

The Grumman F6F Hellcat was originally conceived as an advanced version of the U.S. Navy’s then current front-line fighter, the F4F Wildcat (see NASM collection). The Wildcat’s intended replacement, the Vought F4U Corsair (see NASM collection), first flown in 1940, was showing great promise, but development was slowed by problems, including the crash of the prototype.

The National Air and Space Museum’s F6F-3 Hellcat, BuNo. 41834, was built at Grumman’s Bethpage, New York, factory in February 1944 under contract NOA-(S)846. It was delivered to the Navy on February 7, and arrived in San Diego, California, on the 18th. It was assigned to Fighter Squadron 15 (VF-15) on USS Hornet (CV12) bound for Hawaii. On arrival, it was assigned to VF-3 where it sustained damage in a wheels-up landing at NAS Barbers Point, Hawaii. After repair, it was assigned to VF-83 where it was used in a training role until February 21, 1945. After numerous transfers 41834 was converted to an F6F-3K target drone with the installation of sophisticated radio-control equipment. It was painted red with a pink tail that carried the number 14. Its mission was to be used in Operation Crossroads – the atomic bomb tests at Bikini Atoll. It flew on June 24, 1946, with a pilot, on a practice flight and was launched, unmanned, soon after the first bomb test. Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. Three more manned flights preceded the final unmanned flight on July 25, 1946, which evaluated the first underwater explosion. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible.

F6F-3K 41834 was transferred to NAS Norfolk and logged its last flight on March 25, 1947, with a total of 430.2 flying hours. It was assigned to the National Air Museum on November 3, 1948, and remained at Norfolk until October 4, 1960, when it was moved by barge to Washington and placed in storage. In 1976 this Hellcat was loaned to the USS Yorktown Museum at Charleston, South Carolina. A superficial restoration was performed at the museum, but because of the harsh environment and its poor condition the Hellcat was returned to NASM on March 16, 1982. In 1983, it was sent to Grumman Aerospace where a team of volunteers completely restored the aircraft. In 1985, it was shipped back to the Paul E. Garber Preservation, Restoration and Storage Facility in Suitland, Maryland, and put in storage. NASM’s F6F-3 Hellcat is scheduled to be displayed in the new Steven F. Udvar-Hazy center at Dulles International Airport in Virginia in 2004.

The components aerospace industry in 2012

The aerospace industry has been known to used a respectable volume of composite materials since the 60’s in the construction of aircrafts. At first, commercial airplanes that were going to mass production were mostly made of aluminium, steel, and titanium alloys. The emergence of composites in aeronautic has led to much more efficient, safer, and more economical production of aircrafts and aircraft parts.

The last forty years have seen the aerospace sector undergo a small revolution that results to composites now used for aircrafts and helicopters production. Fibreglass composites were the initial composites to be used by the aerospace industry, followed by carbon fibre and aramid fibre, in the seventies.

The primary uses of composite materials for helicopter and aircraft interior components include the manufacturing of instrument panels, fuselage skin panels, and fuselage fairing panels. Among the principal advantages to use composite materials are the rather low fabrication and installation expenses, additionally to lower toxicity and better resistance to fire.

A great innovation that allows imployment of composites is the ability to fabricate various complex parts and components in one piece (particularly through thermoforming), hence considerably decreasing the various costs associated to machining and to component assembly. Through continued research and technological innovation of aerospace components manufacturer, the advancement of composites has enabled parts to be built with unique chemical and physical characteristics, such parts dedicated for specific uses and complying to the particular needs and requirements of the aerospace sector. Apart from giving the possibility to manufacture durable and reliable parts, this kind of material also provides high resistance to corrosion.

The considerable enthusiasm demonstrate by aircraft manufacturers for those composites is ongoing. Whether for designing aircraft interior parts and components or structural parts, composite materials provide manufacturers with obvious advantages and possibilities when paired to traditional materials and alloys. 

The composites are a big part of the aerospace industry.
