The use of Titanium on the spacecraft was effective in reducing the load by Staff Writers Lake Forest CA (SPX) Dec 08, 2020
For designing or engineering a component of spacecraft, the crucial challenge is weight optimization, and it can't come at the expense of component strength or performance. Materialize Manufacturers and engineers come with the unique idea of using titanium metal and its alloys for the aerospace sector to transfer high mechanical loads in structures like satellites. With optimized design produced through 3D metal Printing, the titanium inserts are generated of the initial weight, with improved properties. It can be used as mounting points to attach devices to spacecraft and satellites. These titanium inserts are highly suitable for heavy loads, lifting a large and heavy structure that means they have to exhibit a great strength-to-weight ratio. It's a part with high specific strength and rigidity but at a minimal weight. The weight reduction will allow the increase of sound equipment to be used in satellites and result in considerable cost savings in each launch. Besides weight reduction, titanium and its alloys resolved thermo-elastic stress issues with spacecraft designs. As the titanium inserts are installed during the curing process of carbon fiber-resistant polymers, they are focused on thermo-elastic stresses.
Properties of Titanium make it a suitable element for aerospace and aeronautics
1. Density
Temperature Resistance
Corrosion Resistance:
Characteristics of Titanium and its alloys make it suitable for the aerospace industry Commercially pure titanium products are selected for chemical resistance. Impurities in titanium can increase its strength, but corrosion resistance becomes lesser. Ti- alloys are ideal for contact with CFRP due to their low CTE and matched galvanic corrosion properties. Titanium alloys are selected for their remarkable strength properties, which depend on several heat-treatments such as quench, age hardening, and temper. The most used titanium alloy is Ti6Al4V, due to broad mechanical and corrosion properties. All classical shaping and forming processes can be used, with wrought products being produced by rolling, forging, extrusion, cast products. Owing to titanium's high similarity for oxygen and other gases, casting and melting processes are carried out under controlled vacuum to prevent infectivity and subsequent property degradation.
Some restriction of using titanium and its alloys
The optimized designs using titanium have reduced vulnerability to stresses and improved load distribution, resulting in increased aerospace industry lifetime. With successful research, manufacturers are looking forward to increasing metal components' implementation in aerospace and aeronautics.

EOS Data Analytics to launch satellite with Dragonfly Multispectral Imagers in 2022 Los Angeles CA (SPX) Oct 27, 2020 EOS Data Analytics has announced the conclusion of an agreement with Dragonfly Aerospace for the delivery of two HR-250 high-performance multispectral imagers. A satellite equipped with the Dragonfly imagers will be launched into Low Earth Orbit (LEO) early in 2022. The side-by-side payloads will allow for the creation of wide swath images in 7 spectral bands at close to 1m resolution. Multispectral images are critical for tracking environmental changes. They allow the monitoring of selected areas ... read more
