Vertiport, eVTOL / Helipad Solutions


BDI’s team is at the forefront in Advanced Air Mobility (AAM) solutions for vertiport / heliport design and eVTOL testing. As the aviation industry evolves, and accessible urban air transportation becomes more of a reality, BDI makes safety a high priority.


Protective designs and materials may play an important role when it comes to downwash and the testing of motor concepts during various weather and wind conditions. Our engineers can examine airflow through the use of computational fluid dynamics (CFD) for particular applications and thrust impacts to various structures, vehicles, equipment or people. Safety is the main priority. Proper advanced planning saves both time and money.

“BDI’s extensive knowledge of acoustics and aerodynamics, along with an extraordinary commitment during the design and construction phases, were critical factors in the overall success of the project.”

Martin Tzschichhold
Project Manager
Airbus Group

“Users of the Billy Bishop Toronto City Airport are able to successfully test aircraft inside the BDI GRE in almost all wind conditions ensuring excellent facility usability.”

Bojan Drakul
Manager – Infrastructure, Planning and Environment

“BDI honored its assumed obligations exactly and correctly with very good quality and within the time limit. I recommend BDI as a stable and correct partner, covering the high international norms and requirements for designing and building of such installations.”

Plamen Stanchev Dimitrov
Executive Director
Sofia Airport

“After more than ten years of service, Emirates Airline continues to be very happy with the GRE facility by BDI, which is used on a daily basis for ground run-ups.”

Robert Aiken
Senior Manager Eng. Facilities

“We sincerely appreciate the outstanding support from Blast Deflectors, Inc. You have obviously earned your reputation over the last 50+ years of service.“


“I walked the entire depth of the parking lot behind the blast fence and there was no significant turbulence even with the engines at full power.”

James Muldoon
Supervisor of Aeronautical Services
Port Authority of New York & New Jersey

“BDI was selected in a public procurement procedure based on its proven technical skills and track record, as well as consideration of its financial offer for the project.”

Gábor Szarvas
Director of Community Affairs, Environment, Health & Safety
Budapest Airport

“The calls have pretty much disappeared since we built the GRE.”

Kelly Ferencz
Project Manager
Detroit Metropolitan Wayne County Airport

“We could not have hoped for a better outcome—the facility not only meets our stringent state noise regulations, but it has also brought some peace and quiet to our neighborhoods.”

Glenn Woodman
Airside Operation Planner
Port of Portland

“The BDI team was professional, responsive and easy to work with throughout the design and construction process. The GRE facility has been in operation for years with a wide variety of aircraft types and continues to function without issue, providing a safe location for engine run-ups.”

Maria Teresa Campo Suarez
Purchasing Manager
Bogotá International Airport

“The CFD study by BDI gave us the data we needed to identify, quantify, and mitigate a jet blast hazard. As a result, our client was able to avoid a situation that would have severely impacted airport operations and created a public hazard.”

Duke Young
AVP, Project Manager

“BDI’s professionalism and commitment to quality, safety and schedule are nothing short of superlative.”

Rocky Johnson
Vice President
Ivey's Construction

“The positive impact of the GRE has been immediate and significant.”

Gene Cabral
Executive Vice President
PortsToronto and Billy Bishop Toronto City Airport

“The enclosure has virtually eliminated complaints related to maintenance run-ups, which had been our top complaint from those in the community.”

RJ Seenstra
President and CEO
Ports Toronto

“Blast Deflectors, Inc. is dedicated to excellence that extends beyond installation.  The user-friendly scheduling tools offered by BDI allow our tenants to effortlessly create, modify, or cancel appointments.  Additionally, the commitment to acoustic excellence ensures not only superior aerodynamics but also a harmonious, noise-reduced environment, making it an easy choice for outstanding performance and tenant satisfaction.”

Stephanie Betts, C.M., ACE
Assistant Director of Operations & Maintenance
Melbourne Orlando International Airport

“During the initial day of construction, we conducted a meeting with the BDI Engineer to share knowledge on past blast deflector installation projects. This session proved highly beneficial for our local engineers, offering an explanation of the process and facilitating a question-and-answer session, thus providing valuable insights.”

Why is BDI the ideal partner for advanced air mobility vertiports?

Ground Testing:

Being a “friendly neighbor” to the community and other operators creates a pleasant work environment and positive impression. Noise from helicopters or eVTOLs (as quiet as they already are) can be a nuisance to others. BDI can assist in identifying noise attenuating solutions for vertiports or testing facilities.

Our team will work with you on uniquely designed testing facilities, protective blast barriers, or noise attenuation walls for a variety of challenges.

Airflow Analysis:

Computational Fluid Dynamics (CFD) consulting projects can involve the examination of operating eVTOL or helicopter aircraft to solve and analyze downwash impacts involving fluid airflow dynamics. CFD modeling techniques uses high-fidelity, three-dimensional CAD models of site configurations representing an accurate portrayal of what’s to be expected in an area and how to identify potential impacts and possible solutions.

Please visit our page for more specific information on CFD analysis.

Vertiport / Heliport Design:

Safety and security are the utmost priority for any airport or vertiport. Regulations and policies are established specifically for these reasons. Being proactive in design and construction for vertiports and helipads can save both time and money through the implementation of specific safety features. With each project being unique in their own way, BDI can recommend solutions to properly protect infrastructure and pedestrians.

Downwash protection from aircraft operations has the potential to cause significant damage to surrounding structures and equipment or injury to people. Maximum wind velocities acceptable to operational areas range between 31 mph (50 km/h) to 50 mph (80 km/h) but could still inflict harm or damage.

Vertiport / heliport operations, at any location, will include the takeoff and landing of eVTOL / helicopters, pedestrians moving to and from loading zones, employees working in the operating area, and use of a variety of equipment. The proximity of advanced air mobility operations to users should consider implementing specific safety features.

BDI has the resources and expertise to assist in evaluating solutions and providing recommendations for vertiports / heliports.
