Comparison between Tejas mk 1 and Tejas mk 2

comparsion between tejas mk and tejas mk 2

Tejas Mk and Tejas Mk 2 are two models of India’s Tejas Light Combat Aircraft (LCA), an indigenously produced fighter aircraft.

In this video, we’ll have a look at the two Tejas fighter jet types, one of which India is now employing and the other of which is scheduled to launch next year while engines are still being developed. Let’s learn more about this fighter jet and what makes these two planes remarkable and one of a kind.

The Tejas Mk1, usually referred to as the HAL Tejas, is a light combat aircraft created for the Indian Air Force (IAF). It is a single-seat, single-engine, multi-role fighter aircraft made to suit the requirements of the Indian armed forces.

while Tejas Mk2, also referred as the Tejas Mark 2, is an upgraded variant of the Tejas, a light combat aircraft (LCA) created by the Indian companies HAL and Aeronautical Development Agency.

The Tejas Mk2 is intended to be a multi-role fighter aircraft with the ability to carry out a variety of tasks, including as air superiority, ground attack, reconnaissance, and electronic warfare.

The Tejas Mk1 has great maneuverability and agility in combat with its delta wing design and tail-less compound delta platform. It has cutting-edge avionics and equipment, including fly-by-wire flying controls, cutting-edge radar, and capability for electronic warfare. The aircraft’s combat radius is about 300 kilometers, and its top speed is Mach 1.8.

The Tejas Mk2 features a combination of cutting-edge composite materials, such as carbon fibre composites, which help to reduce weight and increase structural strength. The aircraft has a quadruplex digital fly-by-wire flight control system, which offers superior handling characteristics and increased maneuverability.

The Tejas Mk1 is equipped with a variety of air-to-air and air-to-surface weapons. It is powered by a single General Electric F404-GE-IN20 engine, which provides a thrust of around 53 kN. Whereas Tejas Mk2 will be propelled by two General Electric F414-GE-INS6 engines, which will deliver more thrust and better performance than the Tejas Mk1’s single engine.

While both variants are members of the same family, there are several notable differences between them. Here’s a comparison between Tejas Mk and Tejas Mk 2:

Size and Weight:
- Tejas MK1: The MK1 has a length of 13.2 meters (43.31 feet) and a wingspan of 8.20 meters (26.90 feet). It has a maximum takeoff weight of around 13,500 kg (29,760 lbs).
- Tejas MK2: The MK2 is slightly larger, with a length of 14.65 meters (48 feet) and a wingspan of 8.50 meters (27.56 feet). Its maximum takeoff weight is expected to be around 17,500 kg (38,580 lbs).
Engine:
- Tejas MK1: The MK1 variant is powered by a single GE F404-GE-IN20 turbofan engine, which provides a maximum thrust of approximately 85 kN (19,000 lbf)
- Tejas MK2: The MK2 variant is expected to feature a more powerful engine, the General Electric F414-GE-INS6 turbofan engine, with a maximum thrust of around 98 kN (22,000 lbf).
Avionics and Electronics:
- Tejas MK1: The MK1 variant is equipped with a range of avionics and electronics, including an advanced glass cockpit, Multi-Mode Radar (MMR), and advanced electronic warfare suite.
- Tejas MK2: The MK2 variant is planned to have upgraded avionics, including an Active Electronically Scanned Array (AESA) radar, advanced electronic warfare systems, and improved sensors.
Payload and Armament:
- Tejas MK1: The MK1 variant has eight hardpoints for carrying various air-to-air and air-to-ground weapons, with a maximum payload capacity of around 5,300 kg (11,700 lb).
- Tejas MK2: The MK2 variant is expected to have an increased payload capacity, with the ability to carry a wider range of weapons, including air-to-air, air-to-ground, and anti-ship missiles.
Performance:
- Tejas MK1: The MK1 variant has a maximum speed of Mach 1.6 (1,980 km/h or 1,230 mph) and a service ceiling of around 16,000 meters.
- Tejas MK2: The MK2 variant has a maximum speed of Mach 1.8 and a service ceiling of around 17,300 m (56,758 ft).

It’s important to remember that the Tejas Mk2 is still in the development stage, and as such, the above-mentioned parameters could change as the project moves forward.

Comparison between Comac C919 and A320 aircraft

The COMAC C919 and the Airbus A320 represent two significant players in the narrow-body commercial aircraft market, each reflecting its manufacturer’s vision for the future of aviation.

The C919, developed by the Chinese aerospace manufacturer COMAC, aims to challenge established Western dominance with its advanced technology and cost-effective design. In contrast, the Airbus A320, a stalwart of global aviation for decades, continues to set benchmarks for efficiency, safety, and passenger comfort.

This comparison explores the key differences and similarities between these two aircraft, highlighting their design philosophies, performance metrics, and market implications.

The COMAC C919, predominantly built using aluminum alloys, is equipped with CFM International LEAP turbofan engines. It has the capacity to accommodate between 156 and 168 passengers in its standard configuration.

This twin-engine jet features a six-abreast economy cabin layout. Initially, it offered options for either CFM56 or IAE V2500 turbofan engines, though the CFM56/PW6000 combination was exclusively used for the A318 model. It can accommodate 195 passengers.

COMAC C919 vs. Airbus A320: A Comparative Overview

Length: The C919 measures 38.9 meters (127.6 feet) in length, slightly longer than the A320, which is 37.57 meters (123 feet 3 inches) long. This extra length provides a marginally larger cabin for the C919.

Wingspan: Both aircraft share the same wingspan of 35.8 meters (117.5 feet), indicating similar aerodynamic properties and potential for comparable fuel efficiency and performance.

Height: The C919 stands at 11.95 meters (39.2 feet) in height, surpassing the A320’s height of 11.76 meters (38 feet 7 inches). This difference is relatively minor but may impact cabin space and cargo hold configuration.

Weight: The COMAC C919 has a maximum takeoff weight of 42,100 kilograms (92,815 pounds), slightly less than the A320’s 42.6 tonnes (93,900 pounds). The A320’s marginally higher weight suggests it may be able to handle slightly more payload or fuel.

Range: The C919 offers a range of 4,630 kilometers (2,500 nautical miles), which is shorter compared to the A320’s range of 6,112 kilometers (3,300 nautical miles). This extended range of the A320 makes it better suited for longer routes and provides airlines with more operational flexibility.
Nearly twice as much as the $50 million that analysts predicted, comac c919 price is roughly $91 million. That is comparable to the cost of the Boeing 737-800 and the Airbus A320neo, which, as of 2021, are estimated to be $106 million and $111 million, respectively.
