Governments are increasingly reluctant to spend money on public transport due to high installation costs and higher up-keep. New systems cannot be easily built because of planning complexity and expense of the land around city areas. Most alternatives are less environmentally friendly than the cars they replace. Terrain and population considerations make engineering roads and railways expensive to install and keep in running condition as land must be extensively surveyed, purchased at market value – enormous in city areas - and surfaces laid with expensive steel and concrete. Bridges, tunnels, stations, service buildings and noise barriers must be constructed as well as substations or other infrastructure for an electric railway system.

Transport congestion is the biggest problem facing planners in every city in the world today. More and more cars are entering roads as people turn away from slow, unreliable public transport. Rail systems are packed to capacity regardless, and for increasing safety standards require more maintenance than ever before.  Building new roads creates bottle necks, leading to more traffic problems and jams. This usually leads to more expense to commuters as more toll booths fill up the highways.

TC Breecuda was conceived extending from average medium to long distance rail fares being bettered by non-subsidised airliners. The design brings these low fares to the short range market along with jet speed. 

All that is required for the TC-500 Breecuda is 80m by 80m platforms in city areas or similar-sized area on the ground in urban areas. These can be constructed above existing railway stations, building tops with clear approaches and routes planned by helicopter. They can fly into any area of the city to disperse the bulk of commuter numbers arriving in one place at about the same time.  Platforms for the TC system will take only 7-12 months to construct: less than a third of the time it would take to build a new road.

The simplicity of TC navigation, refuelling and security facilities would be emplaced. Simultaneously, Breecudas bought tested with around 2-3 weeks of flights in crew familiarisation – who begin training when the system is ordered.  The system will then enter operational service in either a fully automated, semi-automated or manual flight options.

If Hydrogen powered Breecudas are purchased there is the additional benefit of zero smog and pollution. TC is will make money for operators even with its low fares. Virtually all buyers are expected to be Governments augmenting public transport systems. These will then be privatised or leased similar to how many countries rail services operate. The TC will rarely suffer vandalism eliminating the resultant costly damage bills.

» Car cost comparison versus TC Breecuda over a 90 km daily trip to work

These figures reflect a total cost to a commuter using a car, over a round trip distance of 180km demonstrating using a TC Breecuda represents half the cost to a commuter. 

» Daily Costs of a Car: 180 km round trip
Road Tolls excluded
fuel consumption 7 litres per 100km
Fuel used 12.6 litres
180km trip fuel cost at $1.10 per litre $14
Annual contribution to registration and insurance costs per trip $5
Parking $8
Annual tyres, Oil, maintenance and servicing contribution $6
Total car cost per day (excluding car payments and depreciation)= $33
TC Breecuda fare cost =$23.50




 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Time taken: average speed of a car over 90km:

 

90km/hr =1 hr     70km/hr = 1 hr 20 mins.    60km/hr = 1 hr 30 minute

Car 180 km

90km/hr = 2 hrs    70km/hr= 2hrs 40 mins     60km/hr=3hrs

Time taken: average Breecuda speed over 90 km:

non-stop= 11 mins. 1 stop= 16 mins.  2 stops=  21 minutes.  3 stops 26mins.  4 stops 31 mins

Breecuda 180km

4 stops total= 45 mins

» Productivity 

monetary cost to a commuter while travelling 180km round trip each day.

Productivity/work time lost - $20 per hour average wage

Car at an average speed of 90km/hr/ 2hrs 3mins = $41

70km/hr = $53

60km/hr 3hours= $60

Total for a car inclusive at 90km/hr average trip speed = $73

70km/hr= $85

60km/hr=$92 per trip

                 

Daily costs of a car + lost productivity 

90km/hr (average speed) =$68      70km/hr=$80     60km/hr=$87

» TC Breecuda costs: 

4 stops TC 180km total = 45minutes

Station waiting times = 20 minutes

Miscellaneous waiting/commuting= 20 minutes

Fare cost = $23.50

Productivity lost over 1 hr, 25 minutes = $29 

Jet fuel TC 180km total productivity lost plus fare cost = $54.50

Fare Cost= $30

Productivity lost over 1hour, 25 minutes= $29 

Hydrogen fuel TC 180km total productivity lost plus fare cost = $61

 

» Weekly costs 180km round commute

Car cost only = $165

Breecuda fare cost only = $117.50

Car cost over a 5day week + productivity  @90km/hr = $365

@70km/hr = $425

 

Breecuda fare cost + productivity over 1 week:

Jet fuel = $272

Hydrogen =$305

 

» Breecuda Engine programme

 

Jet engines notoriously have higher fuel consumption at low altitude only because these engines are designed for flight at high altitude. By increasing the by-pass ratio to nearly double that of present, as well as reducing the fan pressure ratio these engines can achieve phenomenal economy in comparison to other methods of transport. This will further lower expected economic figures derived from present engines fuel and operational expenses.

 

By-passing double the amount of airflow only increases the blade diameter by about 25% because the area of blade-face is substantially increased with small increases of its radius. Effectively this creates an engine having the economic benefits of low maintenance costs, high reliability and low fuel consumption like turbo-prop aircraft, though the blade will be encased to reduce noise and provide thrust ducting.

 

These developments will be paid for by the Breecuda programme, sponsoring aircraft jet-engine manufacturers with suitable existing power plants to assist in the adaptation of their product to provide economy and power specifically at low altitude. Funding of up to $5 billion will be given to 3 power plant manufacturers to modify existing engines for both TC types.
