What is a Hybrid-Electric Propulsion?

Energy has been in the spotlight in recent years as the need for clean, renewable energy sources has taken center stage. Whether the media is covering stories about climate change, energy conservation or new forms of energy to power the future, developments in the energy sector have received a lot of attention.

Of particular note is the use of energy in the aviation industry, specifically in hybrid aircraft. These are aircraft that use more than one fuel source, and hybrid models have been used in commercial aviation as well as in military applications. Most hybrid aircraft use a mixture of traditional aviation fossil fuel sources and electric power, allowing these aircraft to take advantage of aviation technologies like hybrid-electric propulsion.

How Does Hybrid-Electric Propulsion Work?

Hybrid-electric propulsion is a form of propulsion that relies on electric power and fossil fuels. In some hybrid setups, traditional fuel handles some processes while electricity handles others. Hybrid propulsion systems may also use both types of energy simultaneously.

Typically, the electricity supplied in a hybrid-electric propulsion system will come from onboard batteries. These batteries are rechargeable, and the amount of charge they can hold depends on their size. One downside to this, however, is that batteries used in all-electric vehicles tend to be large and heavy. As a result, they can add extra weight to aircraft, potentially reducing efficiency in the process.

What are the Benefits of Hybrid-Electric Propulsion?

Hybrid-electric propulsion provides several benefits, including the lessening of carbon emissions. When an aircraft is powered by electricity alongside fossil fuels, it tends to emit less carbon compared to using only fossil fuels. This may also reduce the frequency of required maintenance since electric motors and components have fewer moving parts to repair and replace.

Additionally, hybrid-electric propulsion systems are often quieter than their traditional engine counterparts. This not only makes these aircraft good for pilot and crew communication while flying, but it may also be an advantage for stealth missions when using this technology for military purposes.

What is Urban Air Mobility?

If you live in or have visited a major metropolitan area, you already know that traffic can be a hassle. Although big cities provide lots of convenience and access to amenities, they can also be crowded. This poses a challenge for commuter transportation, but it can also be an issue for logistics when it comes to delivering packages and freight across short distances.

To solve these problems, city planners have used innovative approaches, but the aviation industry has also taken note. Aviation experts have been working on plans for what’s known as urban air mobility. This is a scheme that uses unmanned aircraft to handle things like package delivery in cities and densely-populated regions. Small and medium-sized drones are being eyed for air mobility projects, and this kind of delivery may be the future for cities like New York and Los Angeles.

The Benefits of Air Mobility in Urban Areas

There are several benefits of using air mobility setups in urban areas. One of the most obvious is that it can relieve traffic congestion, but it may also be a safer way to get goods from one area of a city to another. When delivery drivers have to brave the traffic to deliver items, the chances for accidents and injuries rise. Unmanned aerial vehicles can safely traverse the skies, far from traffic on the ground, potentially resulting in fewer accidents.

Speed is another advantage of using unmanned drone technology to deliver goods around cities. Because of the aforementioned traffic congestion, deliveries across town can take much longer than they should. When delivery is handled by an aerial vehicle, items can be delivered faster, resulting in improved productivity for business owners who need to get their hands on supplies and items for customers.

The Environmental Impact of Air Mobility in Urban Areas

It’s also worth noting that air mobility projects in large cities may have a positive impact on the environment. Many unmanned aerial vehicles are electric, so they don’t emit carbon like ground vehicles powered by fossil fuel. As a result, air mobility projects may also lead to cleaner air in big cities where pollution is a concern.

3 Things to Know About the Advancement of Aerospace Technology

Aerospace technology has evolved tremendously over the last 30 years. Commercial flights connect the world, making it easier for people to see every corner of the globe. Meanwhile, technologies from NASA and private firms let humans discover the majesty of outer space. We're even on the cusp of commercial space travel.

While it's impossible to go over every advancement of the last few decades, here's what you need to know about the future of aerospace technology.

Addressing Environmental Impact

One major goal in aerospace is finding a more efficient and eco-friendly way to travel by plane. Commercial aviation has a significant impact on the environment. The industry is a massive contributor to greenhouse gases.

Fortunately, exciting innovations are set to change our approach to air travel. Hybrid airplane concepts show that it's possible to dramatically reduce emissions without sacrificing travel efficiency or comfort. These planes use advanced propulsion systems. They can achieve emission-free flights for short flights and hops. On longer flights along the busiest air corridors, they can reduce emissions by up to 76 percent!

Rethinking Modern Air Routes

Many airlines are exploring new travel routes. Today, commercial flights take established air routes between airports. But as more travelers take to the sky, airport congestion and inferior flight experiences create efficiency problems.

Newer aircraft concepts can change the flying experience as we know it. These aircraft don't use traditional jet turbines. They're vertical take-off and landing (VTOL) aircraft that don't require conventional runways. VTOL can handle short hops to city centers and long-range flights, creating more opportunities to establish efficient routes that reduce travel time.

Going Electric

We're starting to see more electric vehicles on the road. In the near future, we'll begin to see similar technology in aircraft! A hybrid airplane can complete short-range flights using nothing but battery power. Some planes are beginning to rely less on fuel for crucial flight tasks, such as taxing and controlling landing gear.

This move to electric operation is beneficial in many ways. In addition to being more environmentally friendly, it reduces costs and decreases our reliance on traditional jet fuel.

The Difference Between Hybrid-Electric vs. Battery-Electric Aircraft

The future of aviation is looking brighter than ever as new technologies emerge to make the industry greener and more efficient. Battery-electric and hybrid electric air travel is paving the way for a new era of advanced air mobility, creating exciting new ways to move passengers, cargo and more.

There are two different technologies innovators continue to explore as the aviation industry moves to achieve its decarbonization goals. These include battery-electric and hybrid-electric propulsion systems. While they both work to make aircraft more environmentally friendly, how do they differ?

Battery-Electric Aircraft

Battery-electric aircraft could be the future of short-range travel. These aircraft do not use conventional jet fuel or sustainable aviation fuel (SAF). Instead, they run entirely on batteries to produce zero emissions.

Typically, all-electric aircraft have a far shorter range than their hybrid or fuel-powered alternatives. But that doesn't mean they don't present many exciting use cases. Experts see battery-electric aircraft as a viable option for short hops. For example, it can be a great solution for air taxis moving people within city centers. Alternatively, it presents a compelling use case for commercial delivery, emergency services and more.

Hybrid Electric Air Travel

While all-electric aircraft presents many unique opportunities for short-range travel, hybrid-electric aircraft opens up more possibilities for cleaner air travel. This technology still uses batteries for more efficient operations. But, aircraft has the added benefit of fuel-powered combustion.

Hybrid-electric aircraft is a more flexible alternative to all-electric aircraft. They can handle short-range travel using nothing but battery power. But when long-range travel is necessary, the propulsion system will automatically move to fuel energy sources. As a result, hybrid-electric designs can handle long-range regional trips, moving through existing air corridors or creating new ones for more efficient travel.

Hybrid technology is also changing current airplanes. Many heavy hitters in the aviation industry are exploring hybridization to improve efficiency for commercial air flights. The hybrid-electric systems can handle tasks like taxiing, pushback and wheel operations. Once the aircraft hits cruising altitude, other power sources can recharge the batteries, enabling them to assist during landing.

Tips on How Airlines Can Decrease Their Carbon Footprint

Heightened awareness about the climate crisis has forced airlines to rethink their strategies and invest in new ones to reduce their carbon footprint. There's an international push to achieve net-zero air by the year 2050. That's not too far away, and airlines are pushing for game-changing innovations.

Here are a few ways airlines can reduce emissions and positively contribute to the growing concern about climate change.

Sustainable Air Fuels

One change that many airlines are embracing is switching from traditional jet fuel to sustainable air fuel (SAF). From an emissions standpoint, SAF creates the same amount of CO2 when burned. However, the savings come from the manufacturing process.

SAF isn't made with traditional fossil fuels. Instead, it's a product of vegetable and waste oils. The manufacturing process absorbs as much as 100 percent of the CO2 created when burned. The offset is substantial. SAF uses feedstock that doesn't compete with crops or contribute to forest degradation. It's a sustainable alternative that many airlines are already using.

Investing in Fuel-Efficient Aircraft

Airlines are already pushing for better fuel efficiency. But the changes are often minimal compared to what's possible.

Many aviation experts believe vertical take-off and landing (VTOL) aircraft are the future. Private VTOL aircraft are more efficient and produce significantly fewer emissions. The best concepts can accept passenger travel while using hybrid-electric propulsion systems.

With all-electric travel for short hops, these aircraft will produce zero emissions. But even on existing air corridors, they generate less than a quarter of what traditional jets do.

Private VTOL aircraft show great promise, flipping the concept of air travel on its head and providing a more eco-friendly alternative to planes. Furthermore, the lack of airstrip space required to take off opens the doors to creating better, more efficient routes.

Better Route Optimization

Where and how an aircraft flies matters. Several factors impact fuel efficiency, but conditions can change rapidly. Airlines can reduce greenhouse gas emissions by investing in on-demand route optimization technology. Optimization can ensure that every flight produces as few emissions as possible when paired with SAF and other sustainability measures.
