  Enhancing Unmanned Operations in Extreme Conditions with the Power of Two-Stroke

  Peter Lietz, Head of International Business Development for Hirth Engines, explains why engine manufacturers must raise the endurance bar for unmanned aerial vehicles (UAVs) to advance capabilities in extreme weather conditions. Drones have become a popular choice for various exploits, from hobbyist aerial photography to large organisations such as Amazon exploring the future of delivery services. In the same vein, governments, militaries and research groups are exploring the use of UAVs to enable highly effective monitoring of unforgiving terrains without risking manned aircraft or land-based patrols. The need for unmanned aerial systems to navigate harsh environments is vital for the maritime, military and commercial sectors. Providing reliable and to the minute information on the status of, and threats to, environments like the Arctic is crucial as governments prepare to take action against significant issues such as climate change and increases in populations. UAVs will play a crucial role in this future considering the need for operators to monitor harsh environments and difficult to reach terrains, especially rotary UAVs. Reaching inhospitable locations can present a variety of logistical challenges, not least of which is the cost of sending land-based patrols or manned aircraft often from navy ships or other maritime vessels. This is where UAVs can enable operators to safely monitor terrains in a cost-effective and efficient way to better understand complex habitats. Carrying out monitoring exercises in areas such as the Artic where there is a real risk to life can be a major challenge. Through the use of well-engineered rotary UAVs, organisations are able to perform a variety of tasks with ease. The responsibility to advance the endurance capabilities of UAVs falls on engine manufacturers. For this reason, we must continue to innovate to increase performance. Over the last few years, rotary UAVs have grown in complexity, not only in terms of the platforms themselves but also the robustness and performance of the engines they run on. As the operational requirements for UAVs grows, engine manufacturers must continually innovate to improve power-to-weight ratios, reduce emissions, and accelerate capabilities in harsh environments. For a long time, fixed-wing UAVs were considered the optimal choice for endurance and speed over their rotary counterparts. However, this is changing rapidly thanks to enhancements in engine design. Rotary UAVs are now becoming a platform of choice due to their reduced logistical footprint and the ability to take off and land in a confined or limited space, especially in maritime environments such as on-board navy ships and coastguard cutters for example. The requirement for rotary UAVs to operate in extreme temperatures such as the cold of the Arctic or the severe heat of warmer climates is essential for operators. This is where two-stroke propulsion engines play a vital role. Two-stroke applications present rotary UAV manufacturers with a range of benefits, including ease of maintenance due to less moving parts and the ability to operate on heavy fuels which are a must for corrosive marine environments. Alongside this, two-stroke powered rotary UAVs are often capable of flying missions with a full payload in extreme conditions for more than five hours without overhaul. With this as a backdrop, it is vital for UAV and engine manufacturers to accelerate the development of propulsion systems capable of operating in extreme locations around the globe. As the industry moves towards hybrid and electric propulsion new challenges will arise and it is crucial that OEMs raise the bar to power the next generation of UAVs. In order to advance the endurance and capabilities of rotary UAVs, engine manufactures must look to innovate the propulsion technology used. Electric is an increasingly popular option for commercial drones. However, electric comes with its own challenges and limitations, such as operational endurance and increased weight of the electrical motors. Considering the performance of batteries in extreme temperatures in comparison to their fuel-based counterparts, there is a long way to go before pure electric UAVs will be capable of flying extended missions in harsh terrains. Hybrid applications that utilise both a combustion engine and electric propulsion systems will provide a bridge toward the future of pure electric flight. A clear advantage for hybrid applications is improving power to weight ratios to enable increased payload capacities. Hybrid UAV applications can be used in various functions, such as: electrically powered take-off and landing with conventional engines powering horizontal flight; or powering flight using only electrical motors whilst the combustion engine acts solely as a generator. In addition, safety is a key purpose behind the pursuit of hybrid applications. For UAV manufacturers, having the ability to convert to an electric battery should the combustion engine fail could make all the difference in enabling a safe landing. Operating UAVs in extreme weather conditions reduces the chances of potential health and safety issues associated with deploying staff or manned systems into harsh environments. In addition, a further key benefit of using UAVs is enabling the deployment of cost-effective systems that perform safely in extreme locations. Ultimately, developing UAVs that can fly farther and for longer in harsh environments will require engine manufacturers to consider alternative fuel and power systems such as heavy fuel two-stroke applications. Heavy fuel is widely considered a must in the maritime industry when dealing with complex environments due to its resistance to extreme temperatures. At Hirth, pairing a robust heavy fuel combustion engine with electrical propulsion is something we are pursuing to advance the future capabilities of unmanned systems and bridge the gap to pure electric flight.

  PBO to examine $60 billion price tag of new warships and compare to other less expensive foreign programs

  David Pugliese, Ottawa Citizen, Postmedia News (dpugliese@ottawacitizen.com) Published: Aug 07 at 6:31 p.m. Updated: a day ago The $60 billion price tag of Canada's proposed new fleet of warships will come under the scrutiny of the Parliamentary Budget Officer, who will also examine other less costly similar projects underway in other countries. The House of Commons government operations committee requested that Parliamentary Budget Officer Yves Giroux examine the cost of the Canadian Surface Combatant project and take a look at the cost of two other types of warships: the FREMM and the Type 31. PBO spokeswoman Sloane Mask said the analysis would be presented to the committee by Oct. 22. “The analytical work is currently underway,” she added. Last year the Liberal government signed an initial deal that is expected to lead to the eventual construction of 15 warships in the largest single government purchase in Canadian history. Lockheed Martin offered Canada the Type 26 warship designed by BAE in the United Kingdom. Irving is the prime contractor and the vessels will be built at its east coast shipyard. Construction of the first ship isn't expected to begin until the early 2020s. But the Canadian Surface Combatant (CSC) program has already faced rising costs. In 2008, the then-Conservative government estimated the project would cost roughly $26 billion. But in 2015, Vice-Admiral Mark Norman, then commander of the navy, voiced concern that taxpayers may not have been given all the information about the program, publicly predicting the cost for the warships alone would approach $30 billion. The overall project is currently estimated to cost around $60 billion. “Approximately one-half of the CSC build cost is comprised of labour in the (Irving) Halifax yard and materials,” according to federal government documents obtained by this newspaper through the Access to Information law. But some members of parliament and industry representatives have privately questioned whether the CSC cost is too high. There have been suggestions that Canada could dump the Type 26 design and go for a cheaper alternative since the CSC project is still in early stages and costs to withdraw could be covered by savings from a less expensive ship. Canada had already been pitched on alternatives. In December 2017, the French and Italian governments proposed a plan in which Canada could build the FREMM frigate at Irving. Those governments offered to guarantee the cost of the 15 ships at a fixed $30 billion, but that was rejected by the Canadian government. Earlier this year, the U.S. Navy selected the FREMM design for its newest fleet of warships. The estimated cost is around $1.3 billion per ship. The other type of warship the PBO will look at is the Type 31, which is to be built for the Royal Navy in the United Kingdom. Those ships are to cost less than $500 million each. In 2017, then Parliamentary Budget Officer Jean-Denis Fréchette estimated the CSC program would cost $61.82 billion. The entry of the BAE Type 26 warship in the Canadian competition was controversial from the start and sparked complaints that the procurement process was skewed to favour that vessel. Previously the Liberal government had said only mature existing designs or designs of ships already in service with other navies would be accepted on the grounds they could be built faster and would be less risky. Unproven designs can face challenges if problems are found once the vessel is in the water and operating. But the criteria was changed and the government and Irving accepted the BAE design, though at the time it existed only on the drawing board. Construction began on the first Type 26 frigate in the summer of 2017 for Britain's Royal Navy.
