  Turkey’s ‘chronic engine problem’ is harming defense projects, warn officials

  By: Burak Ege Bekdil ANKARA, Turkey — Turkey's inability to produce a fully indigenous engine is harming some of the country's otherwise successful domestic defense programs, according to industry and government officials. “We had it 15 years ago, we had it 10 years ago and we are still having it,” said a former defense industry chief. “It's our chronic engine problem.” A government procurement official agreed, telling Defense News that “at best the problem causes major delays, and at worst it can be an existential threat [to programs].” The Altay, a multibillion-dollar program for the production of Turkey's first indigenous tank, has long been delayed due to difficulties surrounding the engine and transmission used to power the new-generation tank. BMC, a Turkish-Qatari joint venture that in 2018 won the serial production contract for the Altay, said in October 2020 that the tank would be fielded within 24 months. The original target was to have the Altay in the field this year 2020. Today, procurement officials and industry sources say even 2022 is an optimistic deadline. Western countries with power pack technology, particularly Germany, have been reluctant to share technology or sell to Turkey for political reasons. “Lack of a feasible power pack [engine and transmission] is depriving the program of any sensible progress,” noted an industry source. Turkey also needs an engine for the new-generation TF-X fighter jet as well as indigenous helicopter models in the making. At the center of these engine efforts is Tusas Engine Industries, a state-controlled engine maker. TEI announced June 19 that it successfully tested its locally made TJ300 miniature turbojet engine, which the company produced for medium-range anti-ship missiles. The engine features a thrust rating of 1.3 kilonewtons. Company officials say the TJ300 engine's more advanced, future versions could power larger anti-ship cruise missiles and land-attack cruise missiles. Turkey hopes to power its anti-ship and land-attack cruise missiles with locally developed engines. “The effort is about ending dependency on imported designs,” a TEI official said. Turkey currently imports miniature air-breathing engines from Microturbo — a unit of French company Safran — to power its domestically developed cruise missiles. Separately, Turkey's Kale Group is developing a larger, albeit miniature turbojet engine called the KTJ-3200. It has a 3.2-kilonewton thrust rating, and will power the Atmaca and SOM missile systems. On a much bigger scale, Kale Group has ambitions to develop an engine to power the TF-X. In 2017, Kale Group and British company Rolls-Royce launched a joint venture to develop aircraft engines for Turkey, initially targeting the TF-X. But the £100 million (U.S. $124 million) deal was effectively put on hold due to uncertainties over technology transfer. In December, Turkish Foreign Minister Mevlüt Çavusoğlu said the government is keen to revive talks with Rolls-Royce. When asked for an update on negotiations, a Rolls-Royce spokesperson told Defense News: “We submitted an engine co-development proposal to Turkey, but the customer has not elected to pursue this to date.” A year before the Kale Group-Rolls-Royce partnership, Turkish Aerospace Industries — a sister company of TEI — signed a $125 million heads of agreement with U.K.-based firm BAE Systems to collaborate on the first development phase of the TF-X. Turkey originally planned to fly the TF-X in 2023, but aerospace officials are now eyeing 2025 at the earliest. TEI is also developing the TS1400, a turboshaft engine it intends to power the T625 Gökbey, a utility and transport helicopter developed and built by TAI. The Gökbey currently flies with the CTS-800A turboshaft engine supplied by Light Helicopter Turbine Engine Company, a joint venture between American firm Honeywell and Rolls-Royce. The Gökbey made its maiden flight in September. TEI says it successfully tested the “core” of its TS1400 turboshaft engine and plans to deliver the prototype to TAI in late 2020. But analysts remain cautious. “These efforts may eventually fail to materialize without meaningful foreign know-how,” said a London-based Turkey specialist. “Or they may come at costs not viable for mass production.” Andrew Chuter in London contributed to this report. https://www.defensenews.com/industry/techwatch/2020/06/26/turkeys-chronic-engine-problem-is-harming-defense-projects-warn-officials/

  Autonomous Firefighting Drone

  Working with mentors from Sikorsky, three University of Connecticut engineering seniors are translating their classroom education to the field. Electrical engineering majors Kerry Jones and Joshua Steil, and computer engineering major Ryan Heilemann, are collaborating to build and program an autonomous firefighting drone to battle blazes without a pilot's guidance. “In the world today there's a high prevalence of forest fires, like in California, but the problem is of how to safely put out these fires,” says Steil. “So our project, in essence, is to see if we can start putting out fires without a human driver.” Once finished, the drone will carry a thermal imaging camera to identify a fire, object avoidance technology to steer clear of any obstacles, and a softball-sized fire-extinguishing ball that will be dropped over the flames. The system's technology will be tied together through coding language developed by the students, and will operate based on inputted coordinates. While their drone will only be able to put out a campfire-size blaze, the project is meant to prove that this technology is possible, so that much bigger technology can be engineered in the future, says Heilemann. “The idea is that in the future, on a larger scale, there can be a fleet of unmanned helicopters that can go out and put out forest fires, thereby lowering loss of life,” says Steil. While drones are currently used by fire departments across the country, all of them so far have a pilot who navigates the drone from a distance, and most are used for observation, not fire suppression. “The autonomy definitely makes it different,” says Jones, “and the fire-extinguishing ball, for sure.” Teams in previous years have worked on similar projects with Sikorsky, which provided some guidance on what has worked and what has not. The team looked back on previous projects' reports, including last year's team, which was the first to integrate firefighting capabilities into the drone. While the previous team to work on this project used small thermal sensors called thermopile array sensors, Heilemann says these sensors required the previous drone to be only about six feet from the flames, which was too close for real-world applications. His team decided to use an infrared camera, which allows for more distance from the flames. This year's team had the added benefit of working on their project in UConn's brand new 118,000 square-foot Engineering and Science Building, which features three engineering floors filled with faculty and labs focused on robotics, machine autonomy, and virtual and augmented reality. At Sikorsky, the team is working with a recent UConn School of Engineering alum, Jason Thibodeau, deputy manager of Sikorsky's Flight Controls and Autonomous Systems Department. “He's really helpful. We have phone meetings every Monday, and we tell him what's going on, what we're struggling with, and he reasons with us,” says Jones. Adds Heilemann, “He really wants us to figure our way through issues we have, instead of just giving us a direct solution.” Working with Sikorsky also introduced the UConn seniors to new career options. Jones has accepted an offer with Sikorsky after she graduates, in their autonomy lab as part of their Rotary and Mission Systems department. Steil has accepted a job offer with Sikorsky's parent company, Lockheed Martin, in Massachusetts after graduation. “Working with Sikorsky definitely sparked a greater interest looking into the company as a whole,” he says. Heilemann also decided to go into the aerospace industry, and has found a job doing control and diagnostics at another aerospace company. Most importantly, the collaboration was a chance to get some experience with a top company. “In this project, I get to learn so much about Sikorsky and what they do,” says Steil, “and having a company like that so close to home and have them be our sponsor is definitely an added benefit.” https://dronescrunch.com/autonomous-firefighting-drone/
