The Martin Jetpack was a single-person aircraft under development. Despite its name, it did not use a jet pack as such, but ducted fans for lift. Martin Aircraft Company of New Zealand (not related to Glenn L. Martin Company, the US company also known as Martin Aircraft) developed it, and unveiled it at the Experimental Aircraft Association's 2008 AirVenture in Oshkosh, Wisconsin, US. The US Federal Aviation Administration classified it as an experimental ultralight airplane.

It used a petrol engine with two ducted fans to provide lift. It was specified to have a maximum speed of 40 km/h (25 mph), a flight ceiling of 2,500 ft (760 m), a range of 15–20 km (9.5–12.5 mi), and endurance of about 28 minutes of flight. Empty weight was 200 kg (440 lb). Martin Aircraft initially planned to target first responders as customers. In 2019, the company closed.

History

The Martin Jetpack was under development for over 30 years. Glenn Neal Martin [1] started work on it in his Christchurch garage in the 1980s. [2]

New Zealand aviation regulatory authorities approved the Martin Jetpack for a limited set of manned flight tests in 2013. [2] As of 2016, the price of the commercial production units was hoped to be US$ 250,000 [3]

Glenn Martin suddenly resigned on 4 June 2015 after investing 30 years in the product.[ citation needed ]

In August 2016, CEO Pete Coker was replaced by the former CFO James West. The company closed its doors in 2019, with KuangChi Science, Martin Aircraft's 52% majority shareholder, looking for a buyer for the few remaining assets.

Description

The Martin Jetpack is a small VTOL device with two ducted fans that provide lift and a 2.0-litre (120 cu in) V4 piston 200- horsepower (150 kW) petrol engine. [4] Although its pilot straps onto it and does not sit, the device cannot be classed as a backpack device because it is too large to be worn while walking. However, the Martin Jetpack does not meet the US Federal Aviation Administration's classification of an ultralight aircraft; it meets weight and fuel restrictions, but it cannot meet the power-off stall speed requirement. The intention is to create a specific classification for the jetpack; it uses the same petrol used in cars, is relatively easy to fly, and is cheaper to maintain and operate than other ultralight aircraft. Most helicopters require a tail rotor to counteract the rotor torque, which, along with the articulated head, complicate flying, construction, and maintenance enormously. The Martin Jetpack is designed to be torque neutral (it has no tail rotor, no collective, no articulating or foot pedals) and this design simplifies flying dramatically. Pitch, roll and yaw are controlled by one hand, height by the other. [5]

Version P12

A further version of the Martin Jetpack was built to prepare for manned flight testing. The new prototype, with the descriptor P12, had several design improvements over earlier versions, including lowering the position of the Martin Jetpack's ducts, which reportedly resulted in better maneuverability. [2] It also had a fully integrated fly-by-wire system. P12 was to be developed into a first responder production model. A lighter personal jetpack was hoped to be available in 2017.

Safety features

To enhance safety, the finished product was to feature a low-opening ballistic parachute along with carbon-fibre landing gear and pilot module. [6]

Flight testing

On 29 May 2011, the Martin Jetpack successfully completed a remotely controlled unmanned test flight to 1,500 m (5,000 ft) above sea level, and carried out a successful test of its ballistic parachute. [7] [8]

A second version, designated prototype P12, of the Martin Jetpack received approval from the New Zealand Civil Aviation Authority (CAA) to begin manned flight testing in August 2013. [2] According to an investor update from August 2016, additional funding would be required to complete the certification process.

Potential markets

In 2015, the company as part of its listing on the Australian Securities Exchange (ASX:MJP) stated that the jetpack could be available on the market in late 2016; it was expected to sell for about US$ 250,000. [3] [9] However, the delivery date was again postponed.

Governments were expected to be a large share of initial consumers. The first production model was aimed at military and first responder emergency crews, such as police, firefighters, and medical personnel, to enable them to have faster response times, to reach areas inaccessible by road, and to get to the top of tall buildings quickly. [9] Interested buyers included the government of the United Arab Emirates; [10] in November 2015, Dubai [ clarification needed ] reportedly had placed an initial order for 20 units, simulators and training, for delivery in 2016.

On 17 June 2005, the CarterCopter became the first rotorcraft to achieve mu-1 (μ=1), an equal ratio of airspeed to rotor tip speed, but crashed on the next flight and has been inoperable since. It is being replaced by the Carter Personal Air Vehicle.

The Hiller YH-32 Hornet was an American ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh 13 lb (5.9 kg) each and deliver an equivalent of 45 hp (34 kW) for a total of 90 hp (67 kW). Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s.

The X-Hawk and its smaller unmanned version, the Tactical Robotics Cormorant, would be used in search and rescue operations where a helicopter would be useless, or at least very dangerous, such as evacuating people from the upper stories of burning buildings, or delivering and extracting police and soldiers while very close to structures, narrow streets, and confined spaces, with a projected size similar to that of a large van.

The Aerial Reconfigurable Embedded System (ARES) was a concept for an unmanned VTOL flight module that can transport various payloads. The concept started as the TX (Transformer) in 2009 for a terrain-independent transportation system centered on a ground vehicle that could be configured into a VTOL air vehicle and carry four troops. ARES' primary function was the same as TX, to use flight to avoid ground-based transportation threats like ambushes and IEDs for units that don't have helicopters for those missions. It was to be powered by twin tilting ducted fans and have its own power system, fuel, digital flight controls, and remote command-and-control interfaces. The flight module would have different detachable mission modules for specific purposes including cargo delivery, CASEVAC, and ISR. Up to 3,000 lb (1,400 kg) of payload would be carried by a module.
