    How The Pentagon Is Reaching Small Suppliers

    Jen DiMascio The Pentagon is employing new ways to track and funnel dollars to small- and medium-sized aviation suppliers hit hard by a drop-off in their commercial business since the novel coronavirus took hold. One way has been to accelerate up-front progress payments to prime contractors. Ellen Lord, the Pentagon's acquisition chief, announced April 30 that in this week alone, the Defense Department processed more than $1.2 billion out of $3 billion to defense contractors in accelerated payments. The acceleration was enabled by a March 20 memo which lifted the amount that large contractors could receive before delivering a contracted item from 80%-90% and for small contractors from 90%-95%. Lord singled out Lockheed Martin for praise for committing to speed $450 million to its supply chain. As those payments are being released, the U.S. Air Force is studying the needs of small suppliers and charting the flow of those progress payments through the industrial base, service officials said during an April 29 Aviation Week MRO webinar. After the first COVID-19 stimulus package was released, Col. Kevin Nalette, vice director, 448th Supply Chain Management Wing, Air Force Sustainment Center, said his office was asked to find out how much money small companies would need to maintain a constant flow of work to continue to support the defense sector. They had two days to ask contractors–the third- and fourth-tier “mom-and-pop shops” whose work becomes an end item purchased somewhere up the stream. The majority of defense vendors do more work–55% or more–for commercial aviation businesses. “As soon as the commercial sector shut down, we had an amazing ability. We now had their full attention,” Nalette said. “When you come to their attention with basically free cash, it's amazing what you can get done.” Tony Baumann, director of contracting for the Air Force Support Center, is capturing data about where the money and progress payments are going. And he is tracking some 2,700 contracts to find out the COVID-related constraints they are operating under. “My guys talked to all of them,” Baumann said, and they stay in contact so that the Air Force knows when a supplier needs to shut down to clean a business. Then Nalette's group is looking at whether that closure might impact deliveries of critical supplies or inventory. That has caused the Air Force to rewrite service contracts using new authorities granted by the CARES Act COVID-relief bill passed by Congress to keep multiple teams of service personnel on contract so that one group can work and another can be ready to backfill so that no group would experience a 14-day interruption, Baumann said. All of those changes are being tracked and coded based on COVID-19, he added. https://aviationweek.com/defense-space/budget-policy-operations/how-pentagon-reaching-small-suppliers

  • Speech Recognition and AI Help Take the Pressure off Aircrew

    Speech Recognition and AI Help Take the Pressure off Aircrew

    Air accidents have decreased in recent years, but when they do occur, the crew's workload is usually at its highest level. Therefore, augmenting crew performance during high workload periods is of great importance and can help maintain flight safety. Aircrew workloads peak when faced with a combination of unpredictable situations: meteorological conditions; high-density traffic; system failures; and flight operations like take-off, climb, descent, approach and landing. The amount of information and number of actions that need to be processed by the crew may become unmanageable, affecting flight safety. The EU-funded VOICI project addressed this threat by developing an intelligent 'natural crew assistant' for the cockpit environment. The system comprises three main technologies, namely sound recording, speech recognition and artificial intelligence. This includes a cockpit-embedded speech-processing system that understands aviation terminology, as well as an array of low-noise optical microphones and optimised array processing for it. The VOICI system also features a new and more efficient speech synthesis, adapted to aviation terminology and noise levels. For further information see the IDTechEx report on Voice, Speech, Conversation-Based User Interfaces 2019-2029: Technologies, Players, Markets. Assessed under realistic conditions Project partners aimed to provide a proof-of-concept demonstrator capable of listening to all communications in the cockpit, both between crew members, and between crew and air traffic control. "The VOICI system should recognise and interpret speech content, interact with the crew, and fulfil crew requests to simplify crew tasks and reduce cognitive workload," outlines project coordinator, Tor Arne Reinen. Researchers also developed a realistic audio evaluation environment for technology experiments. This facilitated the development of the crew assistant and enabled evaluation of its performance, including the speech capture and recognition technologies for use in a noisy cockpit, together with the intelligent dialogue system with automatic speech synthesis as its main output. The audio testing environment involved a 3D physical model of a Falcon 2000S cockpit, including loudspeaker reproduction of noise recordings from a real flight. "We have demonstrated that the crew assistant is feasible under the very high noise levels of an aviation cockpit," Reinen explains. Multiple benefits Speech capture is achieved through both the pilot's headset and an ambient microphone array. Speech recognition using deep neural networks and the dialog system were developed explicitly for the cockpit environment and include aviation terminology and robustness to high levels of background noise. The systems function independently of cloud-based systems and employ dedicated language models for the cockpit scenario. According to Reinen, all the algorithms underlying the dialog system have been implemented and tested: from the Natural Language Understanding unit that understands natural requests to the Dialogue Core which handles the conversation flow. "Particular emphasis has been placed on the ability of the voice assistant to use contextual data," he notes. By reducing crew workload, VOICI will contribute to optimisation of operations, flight safety and crew awareness; better maintenance; reduced cost of operations; and generally higher efficiency and lower stress. "VOICI comprises both small and medium sized enterprises (SMEs) and research institutes, and cooperation within the consortium will contribute to innovation and job creation," Reinen points out. https://www.onartificialintelligence.com/articles/21880/speech-recognition-and-ai-help-take-the-pressure-off-aircrew?rsst2id=193

    Projet Tempest : BAE Systems souhaite fortement recourir à l’impression 3D et à la robotisation

    Le groupe d'armement britannique BAE Systems vient de dévoiler une nouvelle «smart factory» à Warton, au Nord-Ouest de l'Angleterre, pour fabriquer l'avion de combat furtif de sixième génération Tempest. BAE Systems souhaite produire 30% des composants gr'ce à l'impression 3D, et réaliser plus de 50% de l'assemblage gr'ce à des robots intelligents, selon Les Echos. L'objectif est de réduire fortement les coûts et les délais du programme. Les Echos du 23 juillet
